FUNCTION
Comparator A TTL output
Comparator A complementary TTL output
Logic ground. Connect both GND pins to ground.
Comparator A latch enable. QA and –Q– A are latched when LEA is high or floating.
Comparator A latch is transparent when LEA is low.
Not internally connected
Negative power supply: -5V for dual supplies (bypass to GND with a 0.1µF capacitor), or GND for a
single supply
Comparator A inverting input
Comparator A noninverting input
Comparator B noninverting input
Comparator B inverting input
Positive power supply, +5V. Bypass to GND with a 0.1µF capacitor.
Comparator B latch enable. QB and –Q– B are latched when LEB is high or floating.
Comparator B latch is transparent when LEB is low.
Comparator B complementary TTL output
