CD74LPT16374ASM

Overview

The CD74LPT16374ASM is an 8-bit bus driver from the LPT series, manufactured by Harris Corporation. It features two independent functions within a single package, utilizing CMOS technology and housed in a PDSO48 (SSOP) surface-mount package with 48 terminals. The device provides true outputs with three-state capability and includes bus hold inputs to eliminate external pull-up resistors. It operates within a temperature range of -40°C to 85°C, supports a maximum load capacitance of 50 pF, and has a maximum output current of 0.024 A.

Feature Summary

• Integrates two independent 8-bit bus drivers for dual-channel data handling
• Incorporates bus hold inputs to maintain signal integrity without external components
• Provides three-state outputs for effective bus line management

Applications

• High-speed data bus interfacing in digital systems
• Memory address and data bus buffering
• I/O port expansion circuits

Procurement Notes

Verify component authenticity as the part is marked non-RoHS compliant. Confirm the SSOP48 package variant matches design requirements. Check for specific manufacturer lot codes or date codes if traceability is required. Ensure supply chain sources are authorized distributors to avoid counterfeit risks associated with legacy Harris parts.

Selection Notes

Select this component when dual 8-bit latching or driving is required in a compact surface-mount form factor. The LPT series offers high-speed performance suitable for demanding digital applications. Consider the bus hold feature if minimizing external passive components is a priority. Verify voltage compatibility with the target system logic levels before integration.

Part Context

This device belongs to the Harris LPT series of high-speed CMOS logic devices. It is functionally related to other 8-bit bus drivers like the CD74LPT373 but offers dual functionality in a 48-pin package. The part represents legacy semiconductor technology from Harris Corporation, now often sourced through secondary markets.

Replacement Considerations

Check for direct pin-compatible equivalents from manufacturers continuing the LPT line. Verify that any substitute maintains the 48-pin SSOP footprint and identical electrical characteristics, particularly the bus hold functionality and three-state output behavior.
