SN74ALS37ANE4

Overview

The SN74ALS37ANE4 is an octal transparent latch manufactured by Texas Instruments, belonging to the ALS logic series. It features eight D-type inputs and corresponding non-inverting outputs housed in a 20-pin PDIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a propagation delay of 16 ns, a low-level output current capability of 24 mA, and a high-level output current of -2.6 mA. It supports through-hole mounting and functions reliably across an operating temperature range from 0°C to +70°C.

Feature Summary

• Provides eight independent transparent latching channels for data storage
• Utilizes Advanced Low-power Schottky (ALS) technology for optimized performance
• Features non-inverting output polarity for direct signal transmission

Applications

• Parallel-to-serial data conversion circuits
• Bus holding applications in digital systems
• Temporary data storage in microprocessor interfaces

Procurement Notes

Verify the specific ordering suffix 'E' indicates environmental compliance status as defined by the manufacturer. Confirm that the PDIP-20 package matches your PCB footprint requirements. Ensure the ALS logic family characteristics align with your system's power and speed constraints before finalizing procurement.

Selection Notes

Select this component when eight parallel latches are required within a single integrated circuit. The ALS series offers a balance between power consumption and switching speed suitable for general-purpose digital logic. Verify compatibility with existing TTL or LS logic levels if interfacing with other components in the design.

Part Context

This part is part of the SN74ALS373A family of octal latches. The 'SN74ALS37ANE4' designation specifies the commercial temperature grade, through-hole packaging, and lead-free manufacturing process. It serves as a standard solution for managing multiple data lines in synchronous digital designs.

Replacement Considerations

The SN74ALS373AN is the non-compliant equivalent without the environmental suffix. Cross-reference with SN74LS373NE4 for LS-series compatibility, noting differences in propagation delay and drive current.
