The 8mA source and sink drive per channel handles standard CMOS and TTL fan-out without external buffers.
The 0.65mm pitch and 6.5mm body length are standard for 20-pin TSSOP — no footprint surprises when laying out the board. The 8mA per-pin output current keeps trace width modest; no need for wide power pours on a typical 2-layer board.
The 74AHCT family is pin-compatible and functionally identical to the 74HCT245 — same 8-bit transceiver, same 3-state outputs, same 20-pin TSSOP footprint. If your design already uses a 74HCT245 in a 20-TSSOP package, this part swaps in directly with no board change.
