SN54160

The SN54160 is designed as one kind of synchronous 4-bit counters that has xis points of features:(1)internal look-ahead for fast counting;(2)carry output for n-bit cascading;(3)synchronous counting;(4)synchronously programmable;(5)load control line;(6)diode-clamped inputs. SN54160 is fully programmable that is the outputs may be preset to either level, as presetting is synchronous, setting up a low level at the load input disables the counter and cause the outputs to agree with the setup data the next clock pulse regardless of the levels of the enable inputs.

The absolute maximum ratings of the SN54160 can be summarized as:(1)supply voltage, Vcc: 7 V;(2)input voltage: 5.5 V;(3)interemitter voltage: 5.5 V;(4)operating free-air temperature: -55 to +125 ;(5)storage temperature range: -65 to +150 .
