Data Sheet

1. General description
The 74HC245; 74HCT245 is an 8-bit transceiver with 3-state outputs. The device features
an output enable (OE
) and send/receive (DIR) for direction control. A HIGH on OE causes
the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This
enables the use of current limiting resistors to interface inputs to voltages in excess of
V
CC
.
2. Features and benefits
