SN74BCT373DBRG4

Overview

The SN74BCT373DBRG4 is an octal transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It utilizes state-of-the-art BiCMOS design to significantly reduce quiescent current while providing full parallel access for loading. The device operates within a supply voltage range of 4.5 V to 5.5 V and features buffered output-enable inputs to drive bus lines or buffer memory address registers without interface components. It includes ESD protection exceeding 2000-V human-body model standards.

Feature Summary

• State-of-the-art BiCMOS design reduces quiescent current consumption
• Buffered output-enable input allows high-impedance state during power-up or power-down
• Designed specifically for driving highly capacitive or relatively low-impedance loads
• ESD protection exceeds JESD 22 2000-V human-body model standard

Applications

• Implementing buffer registers
• I/O port implementation
• Bidirectional bus drivers
• Working registers

Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's latest documentation to confirm compliance with environmental directives such as RoHS. Confirm that the SSOP package variant matches the required footprint and thermal characteristics for the target application. Ensure compatibility with the specified 4.5 V to 5.5 V operating voltage range.

Selection Notes

Select this component when designing systems requiring octal latching with 3-state outputs capable of driving low-impedance loads. The BiCMOS technology offers lower power consumption compared to standard CMOS alternatives. Consider the SSOP package dimensions and the requirement for a pullup resistor on the OE pin to ensure proper high-impedance behavior during power transitions.

Part Context

This part belongs to the SN74BCT373 family of octal transparent D-type latches. The 'DB' designation indicates the SSOP package, while 'R' signifies tape and reel packaging. The 'G4' suffix typically denotes lead-free and RoHS-compliant manufacturing. This series is engineered for applications needing efficient data storage and bus interfacing in 5 V logic environments.
