Microchip 1533IR22 chip

1533IR22

Digital integrated circuit of transistor logic with Schottky diodes of the TTL series. The

KR1533IR22 chips are an eight-bit register on triggers with a latch with three states at the

output and are designed to control large capacitive or low-impedance loads.

They are used to work in units and units of general-purpose electronic equipment.

Available in a 20-pin plastic package with vertical leads for mounting in PCB holes.

The marking is applied by a numeric-letter code on the chip body.
