Octal inverting buffer with 30
series termination
resistors (3-State)
2
1998 Jan 16
853-1626 18865
FEATURES
Octal bus interface
3-State buffers
Live insertion/extraction permitted
Outputs include series resistance of 30
, making external
termination resistors unnecessary
Output capability: +12mA/–32mA
Latch-up protection exceeds 500mA per Jedec Std 17
ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200 V per Machine Model
Power-up 3-State
Same part as 74ABT240-1
DESCRIPTION
The 74ABT2240 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed.
The 74ABT2240 device is an octal inverting buffer that is ideal for
driving bus lines. The device features two Output Enables (1OE,
2OE), each controlling four of the 3-State outputs.
The 74ABT2240 is designed with 30
series 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 74ABT2240 is the same as the 74ABT240-1. The part number
has been changed to reflect industry standards.
