74LVC162245AX4PA

Overview

The IDT74LVC162245AX4PA is a high-performance, low-power, low-voltage silicon-gate CMOS device belonging to the 74LVC series. It functions as a 16-bit bus transceiver featuring non-inverting, three-state bus-compatible outputs in both send and receive directions. The component incorporates integrated 30-ohm series termination resistors and provides five-volt tolerant inputs and outputs for interfacing with 5V logic systems. It operates within a wide supply voltage range from 1.2V to 3.6V. The device utilizes a MULTIBYTE flow-through standard pin-out architecture with low-inductance multiple power and ground pins to minimize noise and ground bounce.

Feature Summary

• Features integrated 30-ohm series termination resistors for signal integrity
• Provides five-volt tolerant inputs and outputs for mixed-voltage system interfacing
• Utilizes a flow-through standard pin-out architecture for efficient PCB layout

Applications

• Mixed 3.3V and 5V system environments requiring level translation
• High-speed data transmission buses utilizing terminated lines
• General-purpose 16-bit bidirectional data buffering

Procurement Notes

Verify the specific suffix 'X4PA' against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the 74LVC162245A family electrical characteristics. Confirm that the integrated termination resistors meet the target impedance requirements of the application design.

Selection Notes

Select this component when designing systems that require 16-bit bidirectional data transfer between different voltage domains. The integrated 30-ohm termination resistors make it suitable for applications where external series resistors are undesirable. Verify that the operating supply voltage remains within the specified 1.2V to 3.6V range while ensuring input signals do not exceed the absolute maximum ratings.

Part Context

This part belongs to the 74LVC (Low-Voltage CMOS) logic family, which offers performance superior to most advanced CMOS compatible TTL families. The 74LVC162245A variant specifically adds integrated series termination resistors compared to the standard 74LVC162245. The device is manufactured by Integrated Device Technology, now part of Renesas Electronics.

Replacement Considerations

The NXP Semiconductors 74LVC162245A is a functionally equivalent alternative offering identical 16-bit transceiver capabilities with integrated 30-ohm termination resistors and five-volt tolerance. Verify pinout compatibility and electrical parameter alignment before substitution.
