NAME AND FUNCTION
PNP latched input/3–state output (with VX control option)
Data input with special threshold circuitry to reject noise/ open collector output, high
current drive
Enables the B outputs when both pins are low
Enables the A outputs when high
Latched when high (a special feature is buillt in for proper enabling times)
Clamping voltage keeping VOH from rising above VX (VX = Vcc for normal use)
