It handles bidirectional data flow between two 8-bit buses under direction control. Operating from a 4.5V to 5.5V supply, it sources and sinks 24mA per output — enough to drive a heavily loaded backplane or a bank of TTL inputs without external buffers. ## Through-hole DIP package — legacy board fit Housed in a 20-pin DIP (0.300\" width, 7.62mm row spacing), the SN74ACT245N is a through-hole part that drops into existing 0.100\" pitch sockets or wave-solder pads. The supplier device package is 20-PDIP. For a board that already routes 5V logic and has a 20-pin DIP footprint, this is a direct drop-in — no layout change needed from a legacy 74ACT245 or 74HCT245. ## Active lifecycle, no LTB pressure The 74ACT series is a mature logic family with broad installed base; availability is stable through franchised and independent channels. Quoted to order against BOM quantity.","metaTitle":"SN74ACT245N TI 74ACT Transceiver, 24mA, 20-DIP","metaDescription":"Texas Instruments SN74ACT245N 8-bit non-inverting transceiver, 3-state outputs, 24mA drive, 4.5-5.5V supply, -40 to 85°C, 20-DIP.

They are not footprint-compatible. The ABT variant also delivers 32mA output drive versus 24mA, so the bus drive strength differs even if the logic function is the same."},{"question":"What compliance documentation does Texas Instruments provide for SN74ACT245N?","answer":"The part is ROHS3 compliant.
