Synchronous 4-Bit Binary Counters

General Description\nThese synchronous, presettable counters feature an internal carry look-ahead for application in high-speed counting designs. The DM74LS161A and DM74LS163A are 4-bit binary counters. The carry output is decoded by means of a NOR gate, thus preventing spikes during the normal coun ■Synchronously programmable\n■Internal look-ahead for fast counting\n■Carry output for n-bit cascading\n■Synchronous counting\n■Load control line\n■Diode-clamped inputs\n■Typical propagation time, clock to Q output 14 ns\n■Typical clock frequency 32 MHz\n■Typical power dissipation 93 mW;
