CD74LPT16240AMT

Overview

The CD74LPT16240AMT is a bus driver from the LPT series manufactured by Harris Corporation. It features four functional blocks, each handling four bits with inverted outputs. The device utilizes CMOS technology and provides three-state outputs. It is housed in a 48-pin TSSOP package. The component operates within a temperature range of -40°C to 85°C and supports a supply voltage of 2.7V to 3.6V. It has a load capacitance of 50 pF and output currents of 24mA for both high and low states.

Feature Summary

• Provides four independent 4-bit bus drivers with inverted logic functions
• Features three-state outputs for effective bus line management
• Utilizes CMOS technology for compatibility with standard logic families

Applications

• High-speed data bus buffering in digital systems
• Interface circuits requiring signal inversion and isolation
• Memory subsystems utilizing wide data paths

Procurement Notes

Verify the manufacturer designation as Harris Corporation on the component marking. Confirm the package type is TSSOP-48 and the suffix AMT matches the specified operating temperature range. Ensure the part number corresponds to the inverted output variant. Cross-reference the datasheet for specific electrical characteristics relevant to your design requirements.

Selection Notes

Select this component when a 64-bit wide bus interface requires inversion and tri-state control. Consider the 2.7V to 3.6V supply voltage constraint for system power planning. The TSSOP-48 package offers a compact footprint suitable for dense PCB layouts. Verify that the 24mA drive current meets the load requirements of the destination circuitry.

Part Context

This device belongs to the LPT (Low Power Technology) family of bus drivers. It serves as a buffer and line driver for high-speed digital applications. The inverted output configuration distinguishes it from non-inverting counterparts like the CD74LPT244. It is designed for systems requiring reliable data transmission across multiple lines.

Replacement Considerations

The PI74LPT16240AX from Pericom Semiconductor is a documented equivalent offering identical logical functionality and pinout compatibility. Both parts share the same LPT series specifications and package form factor.
