74LVCH162245APAG

Overview

The IDT74LVCH162245APAG is a 16-bit bus transceiver from the LVC/LCX/Z series, manufactured by Renesas (formerly IDT). It features two functional units with true outputs in a 48-pin TSSOP package. The device operates within a supply voltage range of 3 V to 3.6 V and supports LVTTL input and output levels. Key electrical parameters include a maximum propagation delay of 4.7 ns at 50 pF load, with output currents of -24 mA (high) and 24 mA (low). It functions within an industrial temperature range of -40 °C to +85 °C.

Feature Summary

• Provides non-inverting bidirectional data transfer between two 8-bit buses.
• Features low-power CMOS technology compatible with advanced TTL families.
• Includes multiple power and ground pins to minimize noise and ground bounce.

Applications

• Mixed 3.3 V and 5 V system interfacing
• High-density memory modules
• Consumer products requiring low power consumption

Procurement Notes

Verify the manufacturer designation on the component marking, as IDT logic products are now produced under the Renesas brand. Confirm that the specific suffix 'APAG' corresponds to the TSSOP-48 package variant. Ensure the procurement source provides documentation confirming compliance with JEDEC standard no. 8-1A for pinout compatibility.

Selection Notes

Select this component when a 16-bit wide interface is required with LVTTL level compatibility. It is suitable for applications needing low power consumption and direct interface with TTL levels. Verify that the operating voltage requirements align with the 3 V to 3.6 V range and that the TSSOP-48 package fits the board layout constraints.

Part Context

This part belongs to the 74LVC/H family of high-performance, low-voltage silicon-gate CMOS devices. These components are designed to be superior to most advanced CMOS compatible TTL families. The family offers wide supply voltage ranges and 5 V tolerant I/Os, making them ideal for translators in mixed voltage environments.

Replacement Considerations

The NXP Semiconductors 74LVC162245A is a functionally equivalent alternative within the same logic family. Both parts share the 16-bit transceiver architecture and similar pinouts. Verify that the replacement meets the specific voltage and temperature requirements of the original design.
