74LS373P-E

Latches Overview

The Renesas Electronics Corporation 74LS373P-E is an octal D-type transparent latch featuring three-state outputs, designed for high-speed digital logic applications. It operates within a standard voltage range of 4.75 V to 5.25 V and supports a propagation delay of 18 ns at 5 V. The device provides a low-level output current capability of 32 mA and a high-level output current of -2.6 mA. It is housed in a 20-pin DIP package and functions reliably across a commercial temperature range from 0°C to +70°C.

Latches Feature Summary

• Octal D-type transparent latch architecture with common clock and data inputs
• Three-state outputs enabling direct bus connection without external buffers
• High noise immunity characteristics inherent to the LS TTL logic family

Latches Applications

• Parallel-to-serial conversion circuits
• Registering interface signals between microprocessors and peripheral devices
• Driving bus lines in computer systems

Latches Procurement Notes

Verify the specific suffix 'E' against the manufacturer's official documentation to confirm lead-free compliance status and RoHS certification details. Ensure the ordering part number matches the exact package style and temperature grade required for your design specifications before finalizing procurement.

Latches Selection Notes

Select this component when designing systems requiring octal latching with bus isolation capabilities using standard LS TTL logic levels. Consider the 20-pin DIP package constraints for through-hole assembly processes. Evaluate the 18 ns propagation delay against system timing requirements to ensure signal integrity is maintained during data transfer operations.

Latches Part Context

This component belongs to the widely adopted 74LS series of logic integrated circuits, known for balancing speed and power consumption. The 74LS373 variant specifically addresses the need for multi-bit storage elements that can drive high-capacitance loads on shared data buses, serving as a fundamental building block in legacy and industrial digital control architectures.

Latches Replacement Considerations

Compatible substitutes include the Texas Instruments SN74LS373N and the Hitachi HD74LS373P. Verify pinout compatibility and electrical parameter equivalence before substituting.
