Overview
The CD74FCT162244CTSM is an octal buffer and line driver manufactured by Harris Corporation, belonging to the FCT logic series. It features a CMOS construction with true (non-inverting) output polarity and three-state outputs equipped with series resistors. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to 85°C. It is housed in a 48-lead Thin Shrink Small Outline Package (TSSOP).
Feature Summary
- Provides eight non-inverting buffers for signal driving applications.
- Features three-state outputs controlled by low-active enable signals.
- Incorporates bus hold inputs to eliminate the need for external pull-up resistors.
Applications
- High-speed data bus buffering
- Clock distribution networks
- Memory address/data bus drivers
Procurement Notes
Verify the manufacturer origin as Harris Corporation or its successors, noting that this specific part number may be obsolete. Confirm the package type is TSSOP-48 and check RoHS compliance status, as older Harris FCT devices often lack modern environmental certifications. Ensure the datasheet matches the electrical characteristics for the FCT series before procurement.
Selection Notes
Select this component when an octal, non-inverting buffer with three-state capability is required for high-speed digital interfaces. The FCT series offers performance comparable to LS-TTL but with CMOS power consumption. Verify that the system requires bus hold inputs to manage floating lines without external components.
Part Context
This device is part of the Harris CD74FCT162H244 family of octal buffers. It serves as a bridge between microprocessors and peripheral devices, ensuring signal integrity on wide data buses. The TSSOP package allows for compact surface-mount designs in industrial and commercial electronics.
Replacement Considerations
Cross-reference with Texas Instruments CY74FCT162244CTSM or IDT PI74FCT162244ATV for pin-compatible alternatives. Verify that substitute parts maintain the same FCT speed grade and package dimensions.
