Engineering Selection Recommendations
Direct Replacement (Same Package - 48-BSSOP):
CALVC164245IDLREP and SN74ALVC164245DL are direct functional replacements for the 74FCT164245TPVG8, maintaining identical 48-BSSOP packaging and compatible voltage specifications. Both parts are manufactured by Texas Instruments, carry active product status, and maintain RoHS3 compliance with unlimited moisture sensitivity rating. These parts support the required VCCA range (2.3V minimum vs. 2.7V minimum on original) and VCCB range (3V minimum vs. 4.5V minimum on original), making them suitable for applications where the original voltage specifications are met.
Alternative Package Options (48-TSSOP/48-TFSOP):
SN74AVCAH164245GR, SN74AVCA164245VR, SN74AVCH16T245GR, and SN74AVCH16T245VR offer equivalent functionality with alternative package footprints. These parts feature extended voltage ranges (1.4V to 3.6V or 1.2V to 3.6V) that encompass the original specifications, providing greater design flexibility. All maintain active product status and RoHS3 compliance. Package selection depends on PCB layout constraints and thermal management requirements.
Extended Voltage Range Options:
SN74LVC16T245DL and CLVCH16T245MDGGREP provide the widest voltage operating range (1.65V to 5.5V), enabling operation across diverse voltage domains. These parts are suitable for applications requiring maximum voltage flexibility while maintaining the required bidirectional translation architecture and tri-state output configuration.
Avoid:
74VCX163245MTDX carries obsolete product status and should not be selected for new designs despite functional compatibility.
Frequently Asked Questions (FAQ)
Q: Can I use CALVC164245IDLREP as a direct replacement for 74FCT164245TPVG8?
A: Yes. CALVC164245IDLREP maintains identical 48-BSSOP packaging, matching pinout, and compatible voltage specifications. The VCCA range of 2.3V to 3.6V encompasses the original 2.7V to 3.6V specification, and the VCCB range of 3V to 5.5V encompasses the original 4.5V to 5.5V specification. Both parts feature tri-state, non-inverted output configuration and operate across the same temperature range (-40°C to 85°C).
Q: What is the difference between 48-BSSOP and 48-TSSOP packages?
A: Both packages contain 48 pins and are surface-mount options. The 48-BSSOP (0.295" width) and 48-TSSOP (0.240" width) differ in physical dimensions. The 48-TSSOP is narrower, which may affect PCB layout compatibility. Verify footprint compatibility with your PCB design before selecting parts with alternative packages.
Q: Why do some substitute parts have lower minimum voltage specifications?
A: Parts such as SN74AVCAH164245GR (1.4V minimum) and SN74AVCH16T245GR (1.2V minimum) feature extended lower voltage ranges compared to the original 74FCT164245TPVG8 (2.7V minimum). These lower minimums do not affect compatibility when your system operates at the original voltage levels; they simply indicate the part can function across a wider voltage spectrum. Select based on your actual system voltage requirements.
Q: Is the 74VCX163245MTDX suitable for new designs?
A: No. The 74VCX163245MTDX carries obsolete product status. For new designs, select from active parts such as CALVC164245IDLREP, SN74ALVC164245DL, or the SN74AVCAH/SN74AVCH series from Texas Instruments.
Q: What does "tri-state, non-inverted output" mean?
A: Tri-state output means the device can output high, low, or high-impedance (disabled) states, allowing multiple devices to share a common bus without contention. Non-inverted indicates the output logic state matches the input logic state (no inversion occurs during translation).
Q: Can I substitute a part with a wider operating temperature range?
A: Yes. The 74AVC16T245DGG,118 from NXP operates from -40°C to 125°C, which exceeds the original -40°C to 85°C range. This wider range provides additional thermal margin and is fully compatible for applications requiring the original temperature specification.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All listed substitute parts carry RoHS3 compliance status, matching the original 74FCT164245TPVG8 environmental certification requirement.
