74VHC245 74VHCT245 Octal bus transceiver 3-state Rev. 01 25 August 2009 Product data sheet 1. General description The 74VHC245 74VHCT245 are high-speed Si-gate CMOS devices. The 74VHC245 74VHCT245 are octal transceivers featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The 74VHC245 74VHCT245 feature 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 action n Inputs accept voltages higher than V CC n Input levels: u The 74VHC245 operates with CMOS input level u The 74VHCT245 operates with TTL input level n ESD protection: u HBM JESD22-A114E exceeds 2000 V u MM JESD22-A115-A exceeds 200 V u CDM JESD22-C101C exceeds 1000 V n Multiple package options n Specied from - 40 C to +85 C and from - 40 C to +125 C 3.
