The CY74FCT163952 and CY74FCT163H952 are low-power, pin-compatible replacements for the LCX and LPT families, with 5V-tolerant inputs and outputs, 24 mA balanced-drive outputs, power-off disable outputs that permit live insertion, edge-rate control circuitry for reduced noise, FCT-C speed at 4.4 ns, latch-up performance that exceeds JEDEC Standard No. 17, typical output skew less than 250 ps, industrial temperature range of -40˚C to +85˚C, TSSOP (19.6-mil pitch) or SSOP (25-mil pitch), typical Volp (ground bounce) performance that exceeds Mil Std 883D, VCC = 2.7V to 3.6V, ESD (HBM) > 2000V, bus hold on data inputs, eliminates the need for external pull-up or pull-down resistors, devices with bus hold are not recommended for translating rail-to-rail CMOS signals to 3.3V logic levels
The document details the specifications for the Texas Instruments CY74FCT163952 and CY74FCT163H952, which are high-speed, low-power 16-bit registered transceivers. These devices function as a replacement for the LCX and LPT families and support bidirectional data flow between buses A and B.
