Output current is rated 32 mA source, 64 mA sink. That sink figure gives headroom for fan-out to multiple CMOS or TTL inputs without the output voltage creeping out of the guaranteed logic-low window.
Housed in a 56-pin SSOP (7.50 mm body width), surface-mount only.
No. The supply range is 4.5 V to 5.5 V, and the input thresholds are 5 V TTL/CMOS levels. Driving it from a 3.3 V output without a level shifter risks not meeting the VIH(min) threshold.
The CY74FCT16543 is a registered transceiver with latched inputs, while the CY74FCT16652 is a non-inverting transceiver without internal registers. The 16543 adds pipeline storage on the bus; the 16652 is a straight-through buffer. Both are 16-bit, 56-SSOP, 5 V parts.
