Counter Single 4-Bit Async Binary UP/Down 16-Pin SOIC N Rail
Counter Logic IC; Logic Type:Binary Counter; Logic Family:AC; Logic Base Number:74191; Clock Frequency Max:133MHz; Count Maximum:16; Counter Type:Up/Down Counter; Supply Voltage Min:2V; Supply Voltage Max:6V; Termination Type:SMD ;RoHS Compliant: Yes
The AC191 is a reversible modulo 16 binary counter. It features synchronous counting and asynchronous presetting. The preset feature allows the AC191 to be used in programmable dividers. The Count Enable input, the Terminal Count output and the Ripple Clock output make possible a variety of methods of implementing multistage counters. In the counting modes, state changes are initiated by the rising edge of the clock. Product Highlights: ICC reduced by 50% High speed-133 MHz typical count frequency Synchronous counting Asynchronous parallel load Cascadable Outputs source/sink 24 mA
