| The 74VHC123A/221AFT are high speed CMOS MONOSTABLE MULTIVIBRATOR fabricated with silicon gate C2MOS technology. There are two trigger inputs, A input (negative edge), and B input (positive edge). These inputs are valid for a slow rise/fall time signal (tr = tf = 1 s) as they are schmitt trigger inputs. This device may also be triggered by using CLR input (positive edge).After triggering, the output stays in a MONOSTABLE state for a time period determined by the external resistor and capacitor (RX, CX). A low level at the CLR input breaks this state. Limits for CX and RX are:External capacitor, CX: No limit External resistor, RX: VCC = 2.0 V more than 5 kΩ CC ≥ 3.0 V more than 1 kΩ An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltagesWide operating temperature range: Topr = -40 to 125 High speed: Propagation delay time = 8.1 ns (typ.) at VCC = 5 V Low power dissipation: Standby state: 4.0 μA (max) at Ta = 25 Active state: 750 μA (max) at Ta = 25 High noise immunity: VNIH = VNIL = 28 % VCC (min) Power-down protection is provided on all inputs. Balanced propagation delays: tPLH ≈ tPHL Wide operating voltage range: VCC(opr) = 2.0 V to 5.5 V Pin and function compatible with 74HC123,74HC221 type Meer informatie: | | Logic Family: | 74VHC | Logic Function: | Monostable Multivibrator | Number of Elements per Chip: | 27 | Maximum High Level Output Current: | -8mA | Maximum Low Level Output Current: | 8mA | Minimum Pulse Width: | 5 ns | Maximum Propagation Delay Time @ Maximum CL: | 24.5ns | Maximum Quiescent Current: | 80µA | Mounting Type: | Surface Mount | Package Type: | TSSOP | Pin Count: | 16 | Dimensions: | 5 x 4.4 x 1mm | Height: | 1mm | Length: | 5mm | Automotive Standard: | AEC-Q100 |
