Octal bus tranceiver; 3-state
Rev. 1 — 22 July 2013
Product data sheet
1. General description
The 74HC245-Q100; 74HCT245-Q100 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 that enable the use of current limiting resistors to interface inputs to voltages
in excess of VCC.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
2. Features and benefits
Automotive product qualification in accordance with AEC-Q100 (Grade 1)
Specified from 40 C to +85 C and from 40 C to +125 C
Octal bidirectional bus interface
Non-inverting 3-state outputs
Multiple package options
Complies with JEDEC standard no. 7A
ESD protection:
MIL-STD-883, method 3015 exceeds 2000 V
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V (C = 200 pF, R = 0 )
