74ABT845
8-bit bus interface latch with set and reset
(3-State)
1
1995 Sep 06
853-1703 15702
FEATURES
High speed parallel latches
Ideal where high speed, light loading, or increased fan-in are
required with MOS microprocessors
Broadside pinout
Output capability: +64mA/–32mA
Power-up 3-State
Power-up reset
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
DESCRIPTION
The 74ABT845 consists of eight D-type latches with 3-State outputs.
In addition to the LE, OE, MR and PRE pins, the 74ABT845 has two
additional OE pins, making a total of three Output Enable (OE0,
OE1, OE2) pins. The multiple Output enables allow multiuser control
of the interface, e.g., CS, DMA, and RD/WR.
