SN54HC193J[4-BIT SYNCHRONOUS UP/DOWN COUNTERS (DUAL CLOCK WITH CLEAR)]

other part :HC193   SN54HC193   SN74HC193   SN74HC193DT   SN74HC193PWT   SNJ54HC193FK   SNJ54HC193W  

description/ordering information
The ’HC193 devices are 4-bit synchronous, reversible, up/down binary counters. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincidentally with each other when so instructed by the steering logic. This mode of operation eliminates the output counting spikes normally associated with asynchronous (ripple-clock) counters.
The outputs of the four flip-flops are triggered on a low-to-high-level transition of either count (clock) input (UP or DOWN). The direction of counting is determined by which count input is pulsed while the other count input is high.

● Wide Operating Voltage Range of 2 V to 6 V
● Outputs Can Drive Up To 10 LSTTL Loads
● Low Power Consumption, 80-µA Max ICC
● Typical tpd = 20 ns
● ±4-mA Output Drive at 5 V
● Low Input Current of 1 µA Max
● Look-Ahead Circuitry Enhances Cascaded
   Counters
● Fully Synchronous in Count Modes
● Parallel Asynchronous Load for Modulo-N
   Count Lengths
● Asynchronous Clear
