The CY74FCT16245CTPVC is a 16-bit non-inverting transceiver from Cypress's 74FCT series, organized as two 8-bit elements with independent direction and output-enable controls. The 3-state outputs let multiple transceivers share a common data bus without contention. The output drive is specified at 32mA sink and 64mA source — the asymmetric ratio is typical for driving terminated transmission lines where the pull-up network handles the heavier DC load. This matters when the transceiver is driving a heavily loaded backplane with parallel termination resistors to VCC; the 64mA source capability keeps the high-level voltage within noise margin.
Lifecycle and sourcing — active part, no end-of-life risk
It is ROHS3 compliant, which satisfies the majority of global environmental compliance requirements for electronics placed on the EU and similar markets.
Second-source and cross-ship candidates
The closest functional second-source in the 16-bit, 5V, non-inverting transceiver space is the SN74ABT2245DW from TI, which is a single 8-bit element in a 20-SOIC package — not a pin-compatible drop-in. If you need a 16-bit, 5V, 48-SSOP second source, the TI SN74FCT16245T series is the functional equivalent to cross-reference, though verify pinout and timing against your specific revision.
