The 74FCT245CTPGG comes in a 20-TSSOP package with a 0.173-inch (4.40 mm) body width — a compact footprint for bus transceiver functions on dense PCBs. The 0.65 mm pitch demands a fine-pitch solder paste stencil; typical land pattern follows JEDEC MO-153 for TSSOP-20. The 15 mA source / 64 mA sink output drive handles standard TTL loads and lightly loaded backplanes.
Yes — the output type is 3-State, so the bus lines can be driven high, low, or placed in high-impedance (Hi-Z) when the output enable control is inactive. This allows multiple transceivers to share a common bus without contention.
Inputs are 5 V tolerant within that supply range; for 3.3 V interfacing, the part is not specified to accept 3.3 V inputs without a level shifter.
The 74FCT245CTPGG is the 20-TSSOP surface-mount variant of the 74FCT245T, which typically comes in a 20-DIP or 20-SOIC package. The TSSOP package saves board space but requires fine-pitch soldering. Functionally both are 8-bit non-inverting transceivers with 3-state outputs.
