Octal 3-STATE Bus Driver
General Description
This octal 3-STATE bus driver is designed to provide the
designer with flexibility in implementing a bus interface with
memory, microprocessor, or communication systems. This
device offers 64-extended temperature Grade product
guaranteeing performance from 40 C to 85 C. The out-
put 3-STATE gating control is organized into two separate
groups of four buffers, and both control inputs enable the
respective outputs when set logic LOW. The 3-STATE cir-
cuitry contains a feature that maintains the buffer outputs in
3-STATE (high impedance state) during power supply
ramp-up or ramp-down. This eliminates bus glitching prob-
lems that arise during power-up and power-down.
