1 / 15 page TC74HC4538AP/AF/AFN/AFT 2007-10-01 1 TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC4538AP,TC74HC4538AF,TC74HC4538AFN,TC74HC4538AFT Dual Retriggerable Monostable Multivibrator The TC74HC4538A is a high speed CMOS MONOSTABLE MULTIVIBRATOR fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. There are two trigger inputs, A input (positive edge input), and B input (negative edge input). These inputs are valid for a slow rise/fall time signal (tr = tf = 1 s) as they are schmitt trigger inputs. After triggering, the output stays in a MONOSTABLE state for the time period determined by the external resistor and capacitor (RX, CX). A low level at CD input breaks this STABLE STATE. In the MONOSTABLE state, if a new trigger is applied, it makes the MONOSTABLE period longer (retrigger mode). Limitations for CX and RX are as follows: External capacitor CX ........... No limitation External resistor RX.............. VCC = 2.0 V more than 5 kΩ VCC ≥ 3.0 V more than 1 kΩ All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features (Note) • High speed: tpd = 25 ns (typ.) at VCC = 5 V • Low power dissipation Stand by state: ICC = 4 μA (max) at Ta = 25°C Active state: ICC = 300 μA (max) at Ta = 25°C • High noise immunity: VNIH = VNIL = 28% VCC (min) • Output drive capability: 10 LSTTL loads • Symmetrical output impedance: |IOH| = IOL = 4 mA (min) • Balanced propagation delays: tpLH ∼− tpHL • Wide operating voltage range: VCC (opr) = 2 V to 6 V • Pin and function compatible with 4538B Note: In the case of using only one circuit, CD should be tied to GND, T1·T2·Q· Q should be tied to OPEN, the other inputs should be tied to VCC or GND. Note: The JEDEC SOP (FN) is not available in Japan. TC74HC4538AP TC74HC4538AF TC74HC4538AFN TC74HC4538AFT Weight DIP16-P-300-2.54A : 1.00 g (typ.) SOP16-P-300.1.27A : 0.18 (typ.)
