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

•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

of an Nexperia product can reasonably be expected to result in personal

injury, death or severe property or environmental damage. Nexperia and its

minimize the risks associated with their applications and products.

Nexperia does not accept any liability related to any default, damage, costs

or problem which is based on any weakness or default in the customer’s

applications or products, or the application or use by customer’s third party

customer(s). Customer is responsible for doing all necessary testing for the

liability in this respect.

Characteristics sections of this document is not warranted. Constant or

repeated exposure to limiting values will permanently and irreversibly affect

the quality and reliability of the device.
