8-bit bidirectional bus driver — 32 mA sink, 64 mA source
The Texas Instruments CY74FCT543TSOCT is an 8-bit non-inverting transceiver from the 74FCT series, with 3-state outputs on both the A and B ports. Output drive is rated 32 mA high, 64 mA low per channel — that asymmetric sink strength is typical for driving capacitive bus loads or long traces on a backplane without external buffers. The 8-bit width matches an 8-bit data bus or a set of control signals that need to be ganged. Single-element (one 8-bit channel) in a 24-SOIC wide-body package — the 7.50 mm body width is the standard SOIC-24 footprint, so it drops into existing PCB layouts for that form factor without a board spin.
Industrial temp range and field-swap reality
No special derating needed for summer attic or cold-start in a northern warehouse. Surface-mount SOIC-24 with 1.27 mm pitch — a standard fine-tip iron and hot-air station can swap it on site if you have the right solder wick. The wide body gives enough clearance between pins to avoid bridging during rework; no lab bench required, just a steady hand and a flux pen.
Active lifecycle and compliance — no LTB clock ticking
