1 / 16 page 1. General description The 74AHC/AHCT245 is a high-speed Si-gate CMOS device. The 74AHC/AHCT245 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 (OE) input for easy cascading and a send/receive (DIR) input for direction control. OE controls the outputs so that the buses are effectively isolated. 2. Features s Balanced propagation delays s All inputs have a Schmitt-trigger action s Inputs accepts voltages higher than VCC s For 74AHC245 only: operates with CMOS input levels s For 74AHCT245 only: operates with TTL input levels s ESD protection: x HBM JESD22-A114E exceeds 2000 V x MM JESD22-A115-A exceeds 200 V x CDM JESD22-C101C exceeds 1000 V s Multiple package options s Specified from −40 °C to +85 °C and from −40 °C to +125 °C 3.
