74HCT160
FEATURES
- Synchronous counting and loading
- Two count enable inputs for n-bit cascading
- Positive-edge triggered clock
- Asynchronous reset
- Output capability: standard
- ICC category: MSI GENERAL DESCRIPTION
The 74HC/HCT160 are high-speed Si-gate CMOS devices and are pin patible with low power Schottky TTL (LSTTL). They are specified in pliance with JEDEC standard no. 7A. The 74HC/HCT160 are synchronous presettable decade counters which feature an internal look-ahead carry and can be used for high-speed counting. Synchronous operation is provided by having all flip-flops clocked simultaneously on the positive-going edge of the clock (CP). The outputs (Q0 to Q3) of the counters may be preset to a HIGH or LOW level. A LOW level at the parallel enable QUICK REFERENCE DATA GND = 0 V; Tamb= 25 °C; tr = tf = 6 ns TYPICAL SYMBOL PARAMETER t PHL propagation delay CP to Qn CP to TC MR to Qn MR to TC CET to TC propagation delay CP to Qn CP to TC CET to TC maximum clock frequency input...
