74ABT16373CSSC

Overview

The Fairchild Semiconductor 74ABT16373CSSC is a 16-bit transparent D-type latch featuring 3-STATE outputs. It contains sixteen non-inverting latches intended for bus-oriented applications and operates with byte control logic. The device ensures high impedance glitch-free bus loading during power-up and power-down cycles, supporting non-destructive hot insertion. It includes guaranteed latch-up protection compliant with JESD 78 Class II standards.

Feature Summary

• Contains sixteen non-inverting latches with 3-STATE outputs for bus-oriented applications
• Byte-controlled architecture with separate control logic for each octet
• Provides high impedance glitch-free bus loading throughout the entire power-up and power-down cycle
• Supports non-destructive hot insertion capabilities

Applications

• Bus-oriented system data storage
• Byte-controlled memory interface circuits
• Hot-swap data buffering applications

Procurement Notes

Verify the specific CSSC suffix against the manufacturer's official datasheet to confirm package type and temperature range specifications. Ensure compatibility with existing board layouts and voltage levels before procurement. Confirm current availability status as component lifecycles may change.

Selection Notes

Select this component for designs requiring 16-bit parallel data latching with tri-state output control. The ABT series offers speed advantages over standard CMOS families. Verify that the supply voltage and I/O requirements match the target system bus specifications.
