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.

Operate From 1.65 V to 3.6 V
Inputs Accept Voltages to 5.5 V
Max t_pd of 6.3 ns at 3.3 V
Typical V_OLP (Output Ground Bounce)
<0.8 V at V_CC = 3.3 V, T_A = 25°C
Typical V_OHV (Output V_OH Undershoot)
>2 V at V_CC = 3.3 V, T_A = 25°C
Support Mixed-Mode Signal Operation on All Ports (5-V Input/Output Voltage With
3.3-V V_CC)
I_off Supports Live Insertion, Partial-Power-Down Mode, and Back-Drive Protection
Bus Hold on Data Inputs Eliminates the Need for External Pullup or Pulldown Resistors
Latch-Up Performance Exceeds 250 mA Per JESD 17
ESD Protection Exceeds JESD 22
