Product 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 VCC.
2. Features and benefits
Complies with JEDEC standard JESD7A
Input levels:
For 74HC245: CMOS level
For 74HCT245: TTL level
Octal bidirectional bus interface
Non-inverting 3-state outputs
ESD protection:
• • HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
Multiple package options
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
