CD74FCT162244TSM

Overview

The CD74FCT162244TSM is a bus driver from the FCT series, manufactured by Harris Corporation. It features four functional blocks, each handling four bits of data, resulting in an 8-bit wide configuration with true output polarity. The device utilizes CMOS technology and is housed in a 48-pin SSOP package. It operates within a temperature range of -40 °C to 85 °C and supports a maximum supply voltage of 5 V. Key electrical characteristics include a load capacitance of 50 pF, a maximum output current of 0.024 A, and a propagation delay of 4.8 ns at nominal supply. The outputs are three-state with series resistors, and the control type enables the device when the signal is low.

Feature Summary

• Bus hold inputs eliminate the need for external pull-up resistors
• Three-state outputs with integrated series resistors
• Low-enable control logic for active operation

Applications

• High-speed data bus buffering
• Memory interface drivers
• Microprocessor system interconnects

Procurement Notes

Verify the manufacturer origin, as Harris Corporation's semiconductor assets were acquired by Renesas Electronics. Ensure the part number matches the specific SSOP-48 plastic package variant. Confirm that the component meets the required RoHS compliance status, noting that older Harris batches may be non-compliant. Cross-reference the datasheet revision to ensure compatibility with modern design-in requirements.

Selection Notes

Select this component for applications requiring 8-bit bidirectional data transfer with high drive capability. The true output polarity makes it suitable for direct interfacing with standard logic families. Consider the 4.8 ns propagation delay for timing-critical paths. The SSOP-48 package offers a compact footprint for space-constrained designs compared to larger QFP options.

Part Context

This device belongs to the FCT (Fast CMOS) family, designed for high-speed digital applications. It serves as a buffer/driver for quad 4-bit configurations. Similar variants in the series include inverted output versions like the CD74FCT162240 and different pinout configurations. The TSM suffix specifically denotes the shrink pitch SSOP package format used in this iteration.

Replacement Considerations

Check for equivalents such as the IDT 74FCT162244ATPF or Renesas CD74FCT162244ATSM. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
