CD74FCT162827ATSM

Overview

The CD74FCT162827ATSM is a non-inverting buffer manufactured by Harris Corporation, belonging to the FCT logic series. It features two independent elements, each handling ten bits, resulting in a total of twenty data lines. The device utilizes a 56-pin Thin Shrink Small Outline Package (TSSOP/SSOP) with a width of 7.50 mm. It operates on a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to +85°C. Output characteristics include three-state capability with high current drive of 32mA for low state and 64mA for high state.

Feature Summary

• Non-inverting buffer configuration with dual independent ten-bit channels
• Three-state output capability for bus-oriented applications
• High current drive strength supporting 32mA sink and 64mA source loads

Applications

• Bus driver circuits requiring high fan-out
• Clock distribution networks
• Data line buffering in digital systems

Procurement Notes

Verify the manufacturer origin as Harris Corporation, noting that intellectual property may have transferred to Microchip Technology. Confirm the package type is the 56-pin SSOP variant. Ensure compliance with RoHS directives if required, as older Harris parts may not be certified. Cross-reference datasheets for electrical tolerances before integration.

Selection Notes

Select this component when a non-inverting buffer with high current drive is necessary for twenty-line buses. The FCT series offers compatibility with Fast CMOS logic levels. Consider the 56-pin footprint constraints and thermal dissipation requirements for the SSOP package during PCB layout design.

Part Context

This part belongs to the Harris FCT (Fast CMOS Technology) family, designed for high-speed digital applications. The FCT series bridges the performance gap between standard TTL and CMOS technologies. Harris Corporation was a primary producer before its semiconductor division was acquired, affecting current sourcing channels.
