M74HC160

SYNCHRONOUS PRESETTABLE 4-BIT COUNTER

s HIGH SPEED :

fMAX = 62 MHz (TYP.) at VCC = 6V

s LOW POWER DISSIPATION:

ICC =4µA(MAX.) at TA=25°C

s HIGH NOISE IMMUNITY:

) VNIH = VNIL = 28 % VCC (MIN.)

t(s s SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 4mA (MIN)

uc s BALANCED PROPAGATION DELAYS:

d tPLH ≅ tPHL

ro s WIDE OPERATING VOLTAGE RANGE:

P VCC (OPR) = 2V to 6V

s PIN AND FUNCTION COMPATIBLE WITH

ole DESCRIPTION

s The M74HC160 is an high speed CMOS

b SYNCHRONOUS

BCD

DECADE

O PRESETTABLE COUNTER fabricated with silicon

- gate C2MOS technology.

t(s) The CLOCK input is active on the rising edge.

Both LOAD and CLEAR inputs are active LOW.

c Presetting is synchronous on the rising edge of

u 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.
