74FCT163245X4APA

Buffers, Drivers, Receivers, Transceivers Overview

The IDT 74FCT163245X4APA is a 3.3V CMOS 16-bit bidirectional bus transceiver from the 74FCT logic series. It features two independent 8-bit transceivers with 3-state outputs, designed for asynchronous communication between buses. The device operates within a supply voltage range of 2.7V to 3.6V and supports TTL input levels. Key electrical parameters include a maximum propagation delay of 5ns at 50pF load, with output currents of -32mA (high) and 64mA (low). It is housed in a 48-pin SSOP package, suitable for surface mount installation, and functions reliably across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'X4' against the manufacturer's official datasheet to confirm pinout compatibility and electrical characteristics, as suffixes often denote package variations or testing conditions. Ensure the source document explicitly lists this part number to avoid confusion with standard 74FCT163245 variants. Cross-reference the RoHS status and moisture sensitivity level (MSL 3) with current procurement requirements before ordering.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit wide bidirectional data transfers with strict timing constraints. The 5ns propagation delay makes it suitable for moderate-speed synchronous or asynchronous protocols. Consider the 48-pin SSOP package dimensions if board space is limited. Verify that the 3.3V supply rail matches the target system architecture and that TTL input thresholds are compatible with upstream drivers.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74FCT family, which combines Fast CMOS speed with TTL-compatible inputs. Manufactured by IDT (now part of Renesas), these transceivers are widely used in legacy and modern digital designs requiring reliable bus isolation. The 74FCT163245 variant specifically addresses 16-bit data width needs, offering a compact alternative to discrete logic solutions.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes may include Texas Instruments CY74FCT163245APACT or IDT IDT74FCT163245APA, provided the package type and electrical specifications match exactly. Verify that any replacement maintains the same 48-pin footprint and 3.3V operation. Always consult the latest datasheets to ensure functional equivalence regarding drive strength and propagation delay.
