74LV163D中文资料飞利浦数据手册PDF规格书

DESCRIPTION

The 74LV163 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT163.

The 74LV163 is a synchronous presettable binary counter which features an internal look-head 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).

FEATURES

• Optimized for low voltage applications: 1.0 to 3.6 V

• Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V

• Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V, Tamb = 25°C

• Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V, Tamb = 25°C

• Synchronous counting and loading

• Two count enable inputs for n-bit cascading

• Positive-edge triggered clock

• Synchronous reset

• Output capability: standard

• ICC category: MSI
