Advance Information
Dual 4Bit Binary Ripple
Counter
The MC74VHCT393A is an advanced high speed CMOS dual 4bit
binary ripple counter fabricated with silicon gate CMOS technology. It
achieves high speed operation similar to equivalent Bipolar Schottky TTL
while maintaining CMOS low power dissipation.
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 the two binary counters.
Internal flipflops are triggered by hightolow transitions of the clock
input. Reset for the counters is asynchronous and activehigh. State
changes of the 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 VHC393.
The VHCT inputs are compatible with TTL levels. This device can be
used as a level converter for interfacing 3.3 V to 5.0 V because it has full 5
V CMOS level output swings.
The VHCT393A input structures provide protection when voltages
between 0 V and 5.5 V are applied, regardless of the supply voltage. The
output structures also provide protection when VCC = 0 V. These input and
output structures help prevent device destruction caused by supply
voltage—input/output voltage mismatch, battery backup, hot insertion, etc.
The internal circuit is composed of three stages, including a buffer
output which provides high noise immunity and stable output., The inputs
tolerate voltages up to 7 V, allowing the interface of 5 V systems to 3 V
systems.
High Speed: fmax = 170MHz (Typ) at VCC = 5V
Low Power Dissipation: ICC = 4μA (Max) at TA = 25°C
TTLCompatible Inputs: VIL = 0.8 V; VIH = 2.0 V
Power Down Protection Provided on Inputs and Outputs
Balanced Propagation Delays
Designed for 2V to 5.5V Operating Range
Low Noise: VOLP = 0.8V (Max)
Pin and Function Compatible with Other Standard Logic Families
Latchup Performance Exceeds 300mA
ESD Performance: HBM > 2000V; Machine Model > 200V
