PI74ALVCHR162245AE Equivalent & Substitute Parts

Part Overview

The PI74ALVCHR162245AE is a non-inverting transceiver logic IC manufactured by Diodes Incorporated, featuring 2 elements with 8 bits per element and 3-state output capability. Designed for 3.6V operation in a 48-TSSOP package, this component is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, identifying equivalent substitute parts is essential for design continuity and procurement flexibility.

Substitute Part Grouping Explanation

Substitution eligibility for the PI74ALVCHR162245AE is determined by the following critical parameters:

Logic Type: Transceiver, Non-Inverting
Number of Elements: 2
Number of Bits per Element: 8
Output Type: 3-State
Current - Output High, Low: 12mA, 12mA (minimum requirement)
Voltage - Supply: Must support 2.3V ~ 3.6V range or broader
Operating Temperature: -40°C ~ 85°C (TA)
Package / Case: 48-TFSOP or 48-BSSOP (both 48-pin configurations)
Mounting Type: Surface Mount

Substitute parts are grouped into two categories based on package compatibility: 48-TFSOP (direct footprint match) and 48-BSSOP (alternative 48-pin package). All qualified substitutes maintain the core transceiver functionality and electrical specifications required for system compatibility.

Engineering Selection Recommendations

Direct Footprint Compatibility (48-TFSOP):

SN74ALVCHR16245GR and 74ALVC162245PAG8 provide direct footprint compatibility with the PI74ALVCHR162245AE. Both are active products with ROHS3 compliance and MSL 1 rating. SN74ALVCHR16245GR is supplied in Tape & Reel packaging and supports an extended voltage range (1.65V ~ 3.6V). The 74ALVC162245PAG8 from IDT offers dual current output capability (12mA/24mA options) while maintaining the 48-TFSOP footprint.

Alternative Package Compatibility (48-BSSOP):

SN74ALVCHR162245DL and SN74ALVCHR16245LR utilize the 48-BSSOP package, which differs in width (0.295" vs. 0.240") but maintains 48-pin configuration. Both are active products from Texas Instruments with ROHS3 compliance. These options are suitable for designs where PCB layout accommodates the wider package footprint.

Obsolete Product Consideration:

74ALVCH16245PAG from Renesas Electronics maintains functional equivalence but carries obsolete status. This part should be selected only when existing inventory is available and long-term supply is not a requirement.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVCHR16245GR replace PI74ALVCHR162245AE directly?

A: Yes. Both parts share identical logic type, element count, bit configuration, output type, and current specifications. The 48-TFSOP package provides direct footprint compatibility. SN74ALVCHR16245GR supports an extended voltage range (1.65V ~ 3.6V) that encompasses the PI74ALVCHR162245AE requirement (2.3V ~ 3.6V).

Q: What is the difference between 48-TFSOP and 48-BSSOP packages?

A: Both are 48-pin surface mount packages. The 48-TFSOP has a width of 0.240" (6.10mm), while the 48-BSSOP has a width of 0.295" (7.50mm). Footprint compatibility depends on PCB design. Direct replacement requires matching package type unless PCB layout is modified.

Q: Are all substitute parts ROHS3 compliant?

A: SN74ALVCHR162245DL, SN74ALVCHR16245GR, SN74ALVCHR16245LR, and PI74ALVCHR162245AE are confirmed ROHS3 compliant. 74ALVC162245PAG8 compliance status is not specified in the provided data. 74ALVCH16245PAG is ROHS3 compliant but carries obsolete status.

Q: Which substitute offers the best long-term availability?

A: SN74ALVCHR16245GR, SN74ALVCHR162245DL, and SN74ALVCHR16245LR are all active products from Texas Instruments with substantial inventory levels, providing superior long-term supply assurance compared to the obsolete PI74ALVCHR162245AE.

Q: Does output current capability affect substitution eligibility?

A: The PI74ALVCHR162245AE specifies 12mA output current. Substitute parts with equal or higher output current (12mA minimum) are compatible. 74ALVCH16245PAG and 74ALVC162245PAG8 offer 24mA output, which exceeds the requirement and remains compatible for applications designed for 12mA operation.
