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. CD74HCT123M96 -55 to 125 16 Ld SOIC CD74HCT423E -55 to 125 16 Ld PDIP CD74HCT423MT -55 to 125 16 Ld SOIC CD74HCT423M96 -55 to 125 16 Ld SOIC • Q and Q Buffered Outputs • HC Types - 2V to 6V Operation - High Noise Immunity: NIL = 30%, NIH = 30%of VCC at VCC = 5V NOTE: When ordering, use the entire part number. The suffixes 96 and R denote tape and reel. The suffix T denotes a small-quantity reel of 250. 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 5kΩ. The minimum value external capacitance, CX, is 0pF. The calculation for the pulse width is tW = 0.45 RXCX at VCC = 5V. CAUTION: These devices are sensitive to electrostatic discharge. Users should follow proper IC Handling Procedures.
