产品概述
74HC393D,653 is a dual 4-stage binary ripple counter. Each counter features a clock input (n active-low CP), an overriding asynchronous host reset input (nMR) and 4 buffered parallel outputs (nQ0 to nQ3). The counter advances on the HIGH-to-LOW transition of n active-low CP. A HIGH on nMR clears the counter stages and forces the outputs LOW, independent of the state of n active-low CP. Inputs include clamp diodes. This enables the use of current-limiting resistors to interface inputs to voltages in excess of VCC.
- Wide supply voltage range from 2.0V to 6.0V
- CMOS low power dissipation, high noise immunity
- Latch-up performance exceeds 100mA per JESD 78 Class II Level B
- CMOS input levels, two 4-bit binary counters with individual clocks
- Input transition rise and fall rate is 625ns/V max at VCC = 2.0V
- Input leakage current is ±1.0μA max at VI = VCC or GND; VCC = 6.0V
- Total power dissipation is 500mW maximum
- Propagation delay is 190ns max at -40°C to +125°C, VCC = 2.0V
- SO14 package
- Temperature range from -40°C to +125°C
