description
These devices contain six independent 2-input
OR drivers. They perform the Boolean functions
Y = A + B or Y = A
B in positive logic.
The SN54ALS832A and SN54AS832B are
characterized for operation over the full military
temperature range of 55
C to 125
C. The
SN74ALS832A and SN74AS832B are
characterized for operation from 0
C to 70
C.

NOTES: A. CL includes probe and jig capacitance.
B. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
C. When measuring propagation delay items of 3-state outputs, switch S1 is open.
D. All input pulses have the following characteristics: PRR
1 MHz, tr = tf = 2 ns, duty cycle = 50%.
E. The outputs are measured one at a time with one transition per measurement.
