SN74HCT373DWE4

Latches Overview

The SN74HCT373DWE4 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 low power consumption with a maximum ICC of 80 μA and typical propagation delays of 21 ns. It includes eight latches in a single package for full parallel access loading, utilizing TTL-voltage compatible inputs.

Latches Feature Summary

• Features 3-state outputs designed for driving highly capacitive or low-impedance loads
• Transparent D-type latching mechanism controlled by latch-enable input
• TTL-voltage compatible inputs ensure compatibility with standard logic families
• High-current output drive capability supports direct bus line interfacing

Latches Applications

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

Latches Procurement Notes

Verify the specific ordering suffix 'E4' against the manufacturer's current Package Option Addendum to confirm active production status and lead finish specifications. Ensure the SOIC-20 package dimensions match the design footprint requirements. Confirm RoHS compliance details directly from the datasheet documentation before finalizing procurement orders.

Latches Selection Notes

Select this component when designing systems requiring octal data storage with tri-state bus isolation. It is suitable for applications needing TTL-compatible input levels and moderate speed performance. Consider thermal resistance values if operating near maximum temperature limits. Verify that the required output drive current aligns with the specified high-current capabilities for the target load impedance.

Latches Part Context

This part belongs to the SNx4HCT373 family of octal transparent D-type latches. The 'HCT' designation indicates High-speed CMOS technology with TTL-compatible inputs. The 'SN74' prefix denotes commercial grade operation, while the 'DW' suffix specifies the SOIC package style. This series is widely used in digital logic circuits for temporary data storage and signal buffering.

Latches Replacement Considerations

SN74HCT373DWR is a comparable active production variant in the same SOIC-20 package. SN74HCT373N serves as a through-hole alternative in PDIP-20 packaging. Cross-reference the specific electrical characteristics and pinout configurations to ensure functional equivalence during replacement.
