74LVC245A; 74LVCH245A
Octal bus transceiver; 3-state
Rev. 8 — 28 June 2013
Product data sheet
1. General description
The 74LVC245A; 74LVCH245A are 8-bit transceivers featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The device 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.
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to the outputs. These features allow the use of these devices in mixed 3.3 V and 5 V applications.
The 74LVCH245A bus hold on data inputs eliminates the need for external pull-up resistors to hold unused inputs.
