SN74HCT373DW

Latches Overview

The SN74HCT373DW 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 ±6-mA output drive at 5 V with low input current of 1 μA max, ensuring TTL-voltage compatibility. Typical propagation delay is 21 ns, while maximum static current consumption is 80 μA. It is housed in a 20-pin SOIC package.

Latches Feature Summary

• Transparent D-type latching mechanism where outputs follow inputs during the enable phase
• Three-state outputs designed for driving highly capacitive or low-impedance loads
• TTL-voltage compatible inputs with low power consumption characteristics

Latches Applications

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

Latches Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead finish specifications against the latest Package Option Addendum. Ensure handling procedures account for electrostatic discharge sensitivity to prevent performance degradation or failure.

Latches Selection Notes

Select this component when interfacing with TTL-compatible logic families requiring high drive capability. Verify that the operating temperature range meets system requirements. Consider thermal resistance values for PCB layout optimization to ensure reliable operation under load conditions.

Latches Part Context

This part belongs to the SNx4HCT373 family of octal transparent D-type latches. It shares functional similarities with other variants like SN74HC373 but differs in voltage compatibility and speed characteristics. The DW suffix indicates a specific surface-mount package configuration distinct from through-hole alternatives.

Latches Replacement Considerations

SN74HCT373DWR is available as an active production alternative in tape-and-reel packaging.
