74AHC245; 74AHCT245 Octal bus transceiver; 3-state Rev. 05 — 28 April 2009 Product data sheet 1. General description The 74AHC245; 74AHCT245 is a high-speed Si-gate CMOS device. The 74AHC245; 74AHCT245 is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The 74AHC245; 74AHCT245 features an output enable input (OE), for easy cascading, and a send and receive direction control input (DIR). OE controls the outputs so that the buses are effectively isolated. 2. Features n Balanced propagation delays n All inputs have Schmitt-trigger actions n Inputs accept voltages higher than V CC n Input levels: u For 74AHC245: CMOS level u For 74AHCT245: TTL level n ESD protection: u HBM EIA/JESD22-A114E exceeds 2000V u MM EIA/JESD22-A115-A exceeds 200V u CDM EIA/JESD22-C101C exceeds 1000V n Multiple package options n Specified from-40 (cid:176)C to +85 (cid:176)C and from -40 (cid:176)C to +125 (cid:176)C 3.
