74HC245; 74HCT245
Octal bus transceiver; 3-state
Rev. 5 — 14 July 2020
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

• 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
