Philips 74LV161
The 74LV161 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT161. The 74LV161 is a synchronous presettable binary counter which features an internal look-head carry and can be used for high-speed counting. The outputs (Q0 to Q3) of the counters may be preset to a HIGH or LOW level.| Part No. | 74LV161 |

DESCRIPTION
Synchronous operation is provided by having all flip-flops clocked simultaneously on the positive-going edge of the clock (CP). A LOW level at the parallel enable input (PE) disables the counting action and causes the data at the data inputs (D0 to D3) to be loaded into the counter on the positive-going edge of the clock (providing that the set-up and hold time requirements for PE are met). Preset takes place regardless of the levels at count enable inputs (CEP and CET). A low level at the master reset input (MR) sets all fo...
