The SN54LVCH245A octal bus transceiver is designed for 2.7-V to 3.6-V VCC operation, and the SN74LVCH245A octal bus transceiver is designed for 1.65-V to 3.6-V VCC operation. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment.
Operates From 1.65 V to 3.6 V
Inputs Accept Voltages to 5.5 V
Max tpd of 6.3 ns at 3.3 V
Typical VOLP (Output Ground Bounce) <0.8 V at VCC = 3.3 V, TA = 25°C
Typical VOHV (Output VOH Undershoot) >2 V at VCC = 3.3 V, TA = 25°C
Supports Mixed-Mode Signal Operation on All Ports (5-V Input/Output Voltage With 3.3-V VCC)
