General description
The 74HC161 is a synchronous presettable binary counter with an internal look-head carry. Synchronous operation is provided by having all flip-flops clocked simultaneously on the positive-going edge of the clock (CP).

FEATUREs and benefits
■ Complies with JEDEC standard no. 7A
■ Input levels:
    ◆ For 74HC161: CMOS level
■ Synchronous counting and loading
■ 2 count enable inputs for n-bit cascading
■ Asynchronous reset
■ Positive-edge triggered clock
■ ESD protection:
    ◆ HBM JESD22-A114F exceeds 2000 V
    ◆ MM JESD22-A115-A exceeds 200 V
■ Multiple package options
■ Specified from -40 °C to +85 °C and -40 °C to +125 °C
