Description for the CD74HC423

The ’HC123, ’HCT123, CD74HC423 and CD74HCT423 are dual monostable multivibrators with resets. They are all retriggerable and differ only in that the 123 types can be triggered by a negative to positive reset pulse; whereas the 423 types do not have this feature. An external resistor (RX) and an external capacitor (CX) control the timing and the accuracy for the circuit. Adjustment of Rx and CX provides a wide range of output pulse widths from the Q and Q\ terminals. Pulse triggering on the A\ and B inputs occur at a particular voltage level and is not related to the rise and fall times of the trigger pulses.

Once triggered, the output pulse width may be extended by retriggering inputs A\ and B. The output pulse can be terminated by a LOW level on the Reset (R) pin. Trailing edge triggering (A)\ and leading edge triggering (B) inputs are provided for triggering from either edge of the input pulse. If either Mono is not used each input on the unused device (A\, B, and R\) must be terminated high or low.

The minimum value of external resistance, Rx is typically 5k. The minimum value external capacitance, CX, is 0pF. The calculation for the pulse width is tW = 0.45 RXCX at VCC = 5V.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships  tube or tray  devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
