DESCRIPTION

The M54HC161is an high speed CMOS SYNCHRONOUS 4-BIT BINARY PRESETTABLE COUNTER fabricated with silicon gate C 2MOS technology.

The CLOCK input is active on the rising edge.Both LOAD and CLEAR inputs are active LOW.Presetting is synchronous on the rising edge of the clock,the function is cleared asynchronously.Two enable inputs (TE and PE)and CARRY output are provided to enable easy cascading of counters,which facilities easy implementation of N-bit counters without using external gates.

All inputs are equipped with protection circuits against static discharge and transient excess voltage.

CAPACITIVE CHARACTERISTICS

1)C PD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.(Refer to Test Circuit).Average operating current can be obtained by the following equation.I

CC(opr)=C PD x V CC x f IN +I CC

TEST CIRCUIT

L R T =Z OUT of pulse generator (typically 50?)
