Buffer/inverter with 3-state outputs for bus-oriented logic
The CY74FCT16240ATPVCT is a 16-bit buffer/inverter from the 74FCT logic family, organized as four independent 4-bit elements with inverting outputs and 3-state control. The 3-state outputs let multiple devices share a common data bus — each element's output can be driven high, low, or high-impedance, which avoids bus contention when the buffer is not selected. This is the standard architecture for memory-address or peripheral-data buses in legacy 5 V systems.
Output drive and temperature range for industrial backplanes
The buffer sources 32 mA and sinks 64 mA per output. The asymmetric drive — stronger sink than source — matches the typical loading on a 5 V backplane where the capacitive return path dominates. The 0.025-inch lead pitch requires careful solder-paste stencil design for consistent fillet formation across all 48 pins.
Active production — no lifecycle risk for new builds
The 74FCT series is a mature 5 V logic family with a broad installed base.
