The 3-state output enable lets the device disconnect from the bus entirely, which is essential in multiplexed or shared-bus architectures where multiple transceivers share the same data lines. ## Package and board-fit for legacy through-hole The supplier device package is 20-PDIP, which is the same mechanical outline as the 74LS245 and 74ALS245 families. Supplied in tube packaging — the tube is the standard anti-static carrier for DIP parts, suitable for hand assembly or automated insertion machines that handle tube-fed parts. The part is ROHS3 compliant.","metaTitle":"SN74BCT245N 74BCT Transceiver, 3-State, 20-DIP, TI","metaDescription":"Texas Instruments SN74BCT245N 8-bit transceiver, 4.5V-5.5V supply, 3-state outputs, 20-pin DIP.
