4 / 13 page September 1993 4 Philips Semiconductors Product specification Dual retriggerable precision monostable multivibrator 74HC/HCT4538 Fig.4 Functional diagram. Fig.5 Connection of the external timing components Rt and Ct. (1) Connect CTC (pins 1 and 15) to GND (pin 8). FUNCTION TABLE Notes 1. H = HIGH voltage level L = LOW voltage level X = don’t care ↑ = LOW-to-HIGH transition ↓ = HIGH-to-LOW transition = one HIGH level output pulse = one LOW level output pulse INPUTS OUTPUTS nA0 nA1 nRD nQ nQ ↓ LH H ↑ H XX L L H Fig.6 Timing diagram. (1) Positive edge triggering. (2) Positive edge retriggering (pulse lengthening). (3) Negative edge triggering. (4) Reset (pulse shortening). (5) Vref1 and Vref2 are internal reference voltages. (6) T = 0.7 × Rt × Ct (see also Fig.5). |
