CD74LPT16245MT

Overview

The CD74LPT16245MT is a dual-octal bus transceiver manufactured by Harris Corporation, belonging to the LPT series. It features two independent 8-bit non-inverting transceivers with true outputs and three-state capabilities. The device operates within a supply voltage range of 3V to 3.3V and supports bidirectional data flow controlled by a common direction signal. It utilizes a 48-terminal TSSOP shrink pitch package suitable for surface mount applications. The component functions reliably across an industrial temperature range from -40°C to +85°C, offering a typical propagation delay of 4.1 ns at nominal supply.

Feature Summary

• Dual-octal architecture providing two independent 8-bit non-inverting bus transceivers
• Bidirectional data transfer capability managed by a single common control direction signal
• Three-state output design allowing isolation of the bus when disabled
• Compatible with standard TTL and CMOS logic input levels

Applications

• High-density memory module interfacing in embedded systems
• Data routing between microprocessors and peripheral devices
• Bus expansion architectures requiring bidirectional data transfer

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Renesas Electronics. Ensure the specific suffix matches the required package type and that the component meets current environmental compliance standards, noting that original documentation may indicate non-compliance with certain modern regulations.

Selection Notes

Select this component for low-voltage 3.3V systems requiring moderate speed bidirectional data transfer. Compare against newer LVC or LVT families for improved performance metrics. Confirm that the 48-pin TSSOP footprint aligns with the target PCB layout constraints and that the thermal characteristics suit the operating environment.

Part Context

This device belongs to the Harris LPT (Low Power Schottky) logic family, designed for low-power consumption in portable and battery-operated applications. The LPT series was engineered to provide high-speed switching with reduced power dissipation compared to standard LS logic, serving as a bridge between older high-voltage designs and emerging low-voltage standards.
