SN74BCT373NSR

Overview

The SN74BCT373NSR 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 supply current (ICCZ). The device operates within a voltage range of 4.5 V to 5.5 V and features buffered output-enable (OE) inputs for high-impedance control. It supports full parallel access for loading and includes ESD protection exceeding JESD 22 standards, specifically 2000-V human-body model protection.

Feature Summary

• State-of-the-art BiCMOS design reduces ICCZ
• 3-state outputs drive bus lines or buffer memory address registers
• Buffered output-enable input controls logic states or high-impedance state
• ESD protection exceeds JESD 22 2000-V human-body model

Applications

• Implementing buffer registers
• I/O ports
• Bidirectional bus drivers
• Working registers

Procurement Notes

Verify the specific ordering suffix 'NSR' corresponds to the SOP package in tape and reel configuration. Confirm that the component meets the required operating temperature range of 0°C to 70°C for commercial applications. Ensure OE pin handling during power-up aligns with datasheet recommendations to maintain high-impedance states.

Selection Notes

Select this component when requiring octal latching with 3-state capability for bus interfacing. The BiCMOS technology offers lower power consumption compared to standard CMOS alternatives. Verify compatibility with system voltage levels between 4.5 V and 5.5 V. Consider the SOP package dimensions for PCB layout constraints.

Part Context

This part belongs to the SN74BCT series of octal transparent D-type latches. It shares functional similarities with other BCT family members but is distinguished by its specific package and reel packaging. The device is designed for high-speed digital applications requiring low power dissipation and robust bus driving capabilities.
