Quad 3-STATE Buffer
General Description
This device contains four independent gates each of which
performs a non-inverting buffer function. The outputs have
the 3-STATE feature. The 3-STATE circuitry contains a fea-
ture that maintains the buffer outputs in 3-STATE (high
impedance state) during power supply ramp-up or ramp-
down. This eliminates bus glitching problems that arise
during power-up and power-down. To minimize the possi-
bility that two outputs will attempt to take a common bus to
opposite logic levels, the disable time is shorter than the
enable time of the outputs.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
