Overview
The CD74LPT16543CSM is a dual 8-bit registered bus transceiver manufactured by Harris Corporation. It operates on a CMOS technology platform within the LPT series, designed for high-speed data transfer applications. The device features true output polarity and supports bidirectional data flow with independent control capabilities. It is housed in a 56-pin SSOP package, suitable for surface-mount assembly. The component is rated for an operating temperature range of -40°C to 85°C and functions with a supply voltage typically between 2.7V and 3.6V.
Feature Summary
- Dual 8-bit registered bus transceiver architecture
- Independent output enable control for each direction
- Master control functionality for latch operations
- CMOS technology with true output polarity
Applications
- High-speed data bus interfacing
- Bidirectional data buffering systems
- Registered data transmission circuits
Procurement Notes
Verify the manufacturer source carefully, as Harris Corporation's semiconductor assets were acquired by Renesas Electronics. Ensure the part number matches the specific suffix requirements for the SSOP-56 package. Confirm RoHS compliance status, as older Harris parts may not meet current environmental standards. Check for availability from authorized distributors or surplus suppliers holding original stock.
Selection Notes
Select this component when designing systems requiring dual-channel 8-bit data registration with independent direction control. Compare against similar LPT series devices for pin compatibility and electrical characteristics. Consider the 56-pin SSOP footprint constraints during PCB layout. Verify that the 3.3V logic level operation aligns with the system's power supply rails and I/O voltage requirements.
Part Context
This component belongs to the Harris CD74LPT series of low-power Schottky TTL-compatible logic devices. The LPT family was known for high-speed performance and low power consumption. Harris Corporation was a significant player in analog and mixed-signal ICs before its semiconductor division was acquired. This specific transceiver integrates registration capabilities for stable data handling in complex digital systems.
