and 30series termination resistors (3-State)
Product specification
74ABT2245
FEATURES
Octal bidirectional bus interface
3-State buffers
Output capability: +12mA/–32mA
Latch-up protection exceeds 500mA per Jedec Std 17
ESD protection exceeds 2000 V per MIL STD 833 Method 3015
and 200 V per Machine Model
Power-up 3-State
Live insertion/extraction permitted

termination resistors unnecessary
Inputs are disabled during 3-State mode
DESCRIPTION
The 74ABT2245 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed.
The 74ABT2245 device is an octal transceiver featuring
non-inverting 3-State bus compatible outputs in both send and
receive directions. The control function implementation minimizes
external timing requirements. The device features an Output Enable
(OE) input for easy cascading and a Direction (DIR) input for
direction control.
The 74ABT2245 is designed with 30series resistance in both the
High and Low states of the output. This design reduces line noise in
applications such as memory address drivers, clock drivers, and bus
receivers/transmitters.
The 74ABT2245 is the same as the 74ABT245-1. The part number
has been changed to reflect industry standards.
