Onsemi (MC74HC393ADG) Binary Ripple Counter, 50 MHz

Binary Ripple Counter, 50 MHz, 2 V to 6 V, NSOIC-14 Product Overview The MC74HC393ADG is a dual 4-stage binary ripple counter in 14 pin NSOIC package. The device is identical in pin-out to the LS393 device. Its inputs are compatible with standard CMOS outputs with pull-up resistors and it is compatible with LSTTL outputs. This device consists of two independent 4bit binary ripple counters with parallel outputs from each counter stage. A ÷ 256 counter can be obtained by cascading two binary counters Internal flip-flops are triggered by high-to-low transitions of clock input. Reset for counters is asynchronous and active-high. State changes of Q outputs do not occur simultaneously because of internal ripple delays. Therefore decoded output signals are subject to decoding spikes and should not be used as clocks or as strobes except when gated with the Clock of the HC393A. High performance silicon gate CMOS technology 10 LSTTL loads output drive capability and high noise immunity characteristic of CMOS devices Outputs directly interface to CMOS, NMOS and TTL Operating voltage range from 2V to 6V Low input current of 1µA Maximum quiescent supply current (per package) of 4µA at -55°C to 25°C (Vin = VCC or GND, Iout = 0A) In compliance with JEDEC standard number 7.0 A requirements 236 FETs or 59 equivalent gates chip complexity Input rise and fall time of 1000ns at VCC = 2V Operating temperature range from -55°C to 125°C Product Information Logic Family / Base Number: 74HC393 Counter Type: Binary Ripple Clock Frequency: 50MHz Count Maximum: 15 Logic Case Style: NSOIC No. of Pins: 14Pins Supply Voltage Min: 2V Supply Voltage Max: 6V Logic IC Family: 74HC Logic IC Base Number: 74393 Operating Temperature Min: -55°C Operating Temperature Max: 125°C Product Range: - MSL: MSL 1 - Unlimited
