SN74HC160

The SN74HC160-synchronous,presettable counters feature an internal carry look-ahead for application in high-speed counting designs.It is decade counter.Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when so instructed by the count-enable inputs and internal gating.

Features of of the SN74HC160 are: (1)internal look ahead for fast counting; (2)carry output for N-bit cascading; (3)synchronous counting; (4)synchronously programmable; (5)package options include plastic small-outline packages, ceramic chip carriers and standard plastic and ceramic 300-mil DIPs; (6)dependable texas instruments quality and reliability.

The absolute maximum ratings of the SN74HC160 can be summarized as:(1): DC supply-voltage(Vcc) is -0.5 V to 7 V; (2):input diode current, IIK( for Vi<0 V or Vi>Vcc) is ±20 mA; (3): output diode current, IOK(for Vo<0 V or Vo>Vcc) is ±20 mA; (4): continous output current, IO(Vo is 0 to Vcc) is ±25 mA; (5): storage temperature(Tstg) is -65 to +150.
