74ALVC164245GRDR Equivalent & Substitute Parts

Part Overview

The 74ALVC164245GRDR is a voltage level translator IC featuring bidirectional translation capability across 2 circuits with 8 channels per circuit. This component translates signals between VCCA (2.3 V ~ 3.6 V) and VCCB (3 V ~ 5.5 V) voltage domains using tri-state, non-inverted output architecture. The device is packaged in a 54-BGA Microstar Junior (8x5.5) form factor and is manufactured by Texas Instruments.

The 74ALVC164245GRDR has reached obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and system maintenance.

Substitute Part Grouping Explanation

Substitute parts for the 74ALVC164245GRDR are qualified based on the following electrical and mechanical parameters:

Translator Type: Voltage Level (bidirectional capability required)
Channel Configuration: 2 circuits with 8 channels per circuit
Voltage Compatibility: VCCA range 2.3 V ~ 3.6 V and VCCB range 3 V ~ 5.5 V
Output Architecture: Tri-State, Non-Inverted
Operating Temperature Range: -40°C ~ 85°C (TA)
Mounting Type: Surface Mount

The identified substitute parts maintain functional equivalence through identical circuit topology and electrical specifications. Package form factor differences (54-BGA to 48-TSSOP) represent a mechanical change that requires PCB layout redesign but does not affect electrical performance within the specified parameter ranges.

Engineering Selection Recommendations

Both substitute parts maintain active product status, ensuring long-term availability and manufacturing support. The 74ALVC164245PAG (IDT) and 74FCT164245TPAG (Renesas) are electrically equivalent within the specified voltage and temperature operating ranges.

The 74FCT164245TPAG carries explicit ROHS3 compliance and REACH unaffected certification, matching the regulatory status of the original 74ALVC164245GRDR. The 74ALVC164245PAG regulatory certifications are not specified in the provided data.

Package migration from 54-BGA to 48-TSSOP requires PCB layout modification. Both substitute parts use identical 48-TFSOP packaging, enabling direct footprint compatibility between the two alternatives.

Frequently Asked Questions (FAQ)

Q: Can the 74ALVC164245PAG and 74FCT164245TPAG be used interchangeably with the 74ALVC164245GRDR?

A: Both parts maintain electrical equivalence in translator type, circuit configuration, channel count, output architecture, and operating temperature range. Package form factor differs (54-BGA versus 48-TSSOP), requiring PCB redesign. Voltage ranges for VCCA and VCCB are compatible within the specified operating conditions.

Q: What is the primary difference between the 74ALVC164245PAG and 74FCT164245TPAG?

A: Both parts share identical electrical specifications and package form factor (48-TSSOP). The primary difference is manufacturer: IDT for the 74ALVC164245PAG and Renesas for the 74FCT164245TPAG. The 74FCT164245TPAG explicitly documents ROHS3 compliance and REACH unaffected status.

Q: Does the package change from 54-BGA to 48-TSSOP affect electrical performance?

A: Package form factor is a mechanical consideration only. Electrical performance remains equivalent when operating within the specified voltage and temperature ranges. PCB layout and routing must be redesigned to accommodate the different pin configuration and package dimensions.

Q: Are there voltage range limitations when substituting these parts?

A: The substitute parts specify VCCA range of 2.7 V ~ 3.6 V, compared to the original 2.3 V ~ 3.6 V. If your design operates VCCA below 2.7 V, the substitute parts are not suitable. VCCB ranges are compatible (4.5 V ~ 5.5 V for substitutes versus 3 V ~ 5.5 V for original).

Q: What is the inventory status of these substitute parts?

A: 74ALVC164245PAG: 2880 Pcs New Original In Stock. 74FCT164245TPAG: 1219 Pcs New Original In Stock. Both parts are available for immediate procurement.
