74AHC123A; 74AHCT123A Dual retriggerable monostable multivibrator with reset Rev. 02 — 18 January 2008 Product data sheet 1. General description The 74AHC123A; 74AHCT123A are high-speed Si-gate CMOS devices and are pin compatible with Low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74AHC123A; 74AHCT123A are dual retriggerable monostable multivibrators with output pulse width control by three methods. The basic pulse time is programmed by selection of an external resistor (REXT) and capacitor (CEXT). The external resistor and capacitor are normally connected as shown in Figure 11. Once triggered, the basic output pulse width may be extended by retriggering the gated active LOW-going edge input (nA) or the active HIGH-going edge input (nB). By repeating this process, the output pulse period (nQ = HIGH, nQ = LOW) can be made as long as desired. Alternatively an output delay can be terminated at any time by a LOW-going edge on input nRD, which also inhibits the triggering. An internal connection from nRD to the input gate makes it possible to trigger the circuit by a positive-going signal at input nRD as shown in Table 3. Figure 8 and Figure 9 illustrate pulse control by retriggering and early reset. The basic output pulse width is essentially determined by the value of the external timing components REXT and CEXT. When CEXT ≥ 10 nF, the typical output pulse width is defined as: tW = REXT × CEXT where tW = pulse width in ns; REXT = external resistor in kΩ; CEXT = external capacitor in pF. Schmitt-trigger action at all inputs makes the circuit highly tolerant to slower input rise and fall times. The 74AHC123A; 74AHCT123A is identical to the 74AHC423; 74AHCT423 but can be triggered via the reset input. 2.
