Поставка оригинальных CD74AC14MG4, Логические элементы - Вентили и инверторы, от Texas Instruments

DescriptionCD4532BMS consists of combinational logic that encodes the highest priority input (D7 - D0) to a 3-bit binary code.
The eight inputs, D7 through D0, each have an assigned priority; D7 is the highest priority and D0 is the lowest.
The priority encoder is inhibited when the chip-enable input E1 is low. When E1 is high, the binary representation of the highestpriority input appears on output lines Q2 - Q0, and the group select line GS is high to indicate that priority inputs are present.
The enable-out (EO) is high when no priority inputs are present. If any one input is high, EO is low and all cascaded lower-order stages are disabled.
