SN74HCT373PWT

Latches Overview

The SN74HCT373PWT is an octal transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features high-current true outputs capable of driving up to 15 LSTTL loads. The device provides typical propagation delays of 21 ns and ±6-mA output drive at 5 V. It utilizes a TSSOP-20 package, supports a maximum ICC of 80 μA, and includes TTL-voltage compatible inputs.

Latches Feature Summary

• Features eight high-current latches in a single package for full parallel access loading
• Provides 3-state outputs designed specifically for driving highly capacitive or low-impedance loads
• Includes an output-enable input that places outputs in normal logic states or high-impedance state

Latches Applications

• Buffer registers
• I/O ports
• Bidirectional bus drivers
• Working registers

Latches Procurement Notes

Verify the specific ordering suffix 'PWT' against the manufacturer's current Package Option Addendum to confirm availability status and lead time requirements. Ensure the procurement channel sources components from authorized distributors to guarantee authenticity and traceability. Confirm RoHS compliance and moisture sensitivity level ratings prior to finalizing orders.

Latches Selection Notes

Select this component when interfacing with TTL-compatible logic families requiring 3-state control. Verify that the system operating temperature falls within the -40°C to +85°C range. Ensure the power supply voltage remains strictly between 4.5 V and 5.5 V. Consider the TSSOP-20 package dimensions for PCB layout constraints and thermal management requirements.

Latches Part Context

This part belongs to the SNx4HCT373 family of octal transparent D-type latches. It shares functional characteristics with other variants such as SN74HCT373DW and SN74HCT373N, differing primarily in packaging and manufacturing revisions. The HCT series ensures compatibility with standard TTL logic levels while offering CMOS power consumption benefits.
