74ABT373APW,112

Overview

The NXP USA Inc. 74ABT373APW,112 is an octal transparent latch with 3-State output buffers manufactured by Philips Semiconductors (now NXP). It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of -40°C to +85°C. The device features propagation delays of 3.2ns (typical) from data inputs to outputs at 5V. It provides high output drive capability of +64mA/-32mA and includes power-up 3-State functionality for live insertion support.

Feature Summary

• Octal transparent latch design with independent Enable and Output Enable control gates
• High-output drive capability suitable for heavily loaded buses and MOS memories
• Power-up 3-State feature enabling safe live insertion and extraction operations

Applications

• Driving heavily loaded 3-State buses
• Interfacing with MOS memories
• Connecting to MOS microprocessors

Procurement Notes

Verify the specific package type against the ordering information table, as the PW suffix denotes a 20-pin Plastic TSSOP Type I package. Confirm that the component meets the required temperature range specifications for your application environment. Ensure compatibility with the 4.5V to 5.5V supply voltage limits defined in the recommended operating conditions.

Selection Notes

Select this component when an octal latch with high-speed BiCMOS performance is required. It is suitable for applications needing robust output drive capabilities and ESD protection exceeding 2000V per MIL STD 883 Method 3015. Consider the 20-pin TSSOP package constraints if space is limited compared to standard SOIC or DIP options.

Part Context

This part belongs to the 74ABT series of high-performance BiCMOS logic devices. It combines low static and dynamic power dissipation with high speed. The device is functionally similar to other octal latches but offers enhanced drive strength and faster propagation delays typical of the ABT family architecture.

Replacement Considerations

Check for equivalent parts in the 74ABT series with different package suffixes such as D (SO) or DB (SSOP) if pinout compatibility allows. Verify that any substitute maintains the same 3-State buffer characteristics and voltage operating ranges.
