74FCT16245TPA

Buffers, Drivers, Receivers, Transceivers Overview

The IDT74FCT16245TPA is a 16-bit bidirectional bus transceiver utilizing 0.5-micron CMOS technology. It operates within the 74FCT logic family and supports two independent 8-bit channels or one 16-bit configuration. The device features TTL-compatible inputs, high-drive outputs (-32mA I_OH, 64mA I_OL), and power-off disable capability for live insertion. It is housed in a 48-pin SSOP package with an industrial temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• High-speed synchronous communication between two busses using dual metal CMOS technology
• Configurable as two independent 8-bit transceivers or one 16-bit transceiver via direction control
• Power-off disable outputs permit live insertion into backplanes without system disruption

Buffers, Drivers, Receivers, Transceivers Applications

• Synchronous communication between two busses (A and B)
• Driving high-capacitance loads and low-impedance backplanes
• Live insertion applications requiring board hot-swapping capabilities

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'TPA' against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with required voltage levels and load conditions before procurement. Cross-reference ordering codes with current Renesas or IDT catalogs to avoid obsolete variants.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high drive strength and low output skew are required for bus interfacing. Consider the 74FCT series for TTL-to-CMOS compatibility. Evaluate thermal performance within the specified industrial range. Confirm that the SSOP package fits the available PCB footprint constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the IDT 74FCT16245T/AT/CT/ET family of fast CMOS 16-bit bidirectional transceivers. These devices serve as high-speed, low-power replacements for older ABT functions. The family includes military and industrial temperature variants packaged in SSOP, TSSOP, and CERPACK formats.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct equivalents such as IDT74FCT16245TPAG or other suffixes within the same FCT16245T family. Verify pinout and electrical characteristics match exactly. Consult manufacturer substitution guides for cross-brand alternatives if IDT parts are unavailable.
