SYNCHRONOUS COUNTERS WITH OUTPUT REGISTERS AND MULTIPLEXED 3-STATE OUTPUTS
SN74LS691N is a 4-bit binary counter with multiplexed 7-segment display driver, manufactured by Texas Instruments.
Description:
The SN74LS691N is a 4-bit binary counter with multiplexed 7-segment display driver. It is a 20-pin dual in-line package (DIP) device, with a maximum operating voltage of 5V. It has four 4-bit binary counters, each with its own clock input (CP0-CP3) and four multiplexed 7-segment display drivers. The outputs of the counters are connected to the inputs of the display drivers, which drive the 7-segment displays. The SN74LS691N also has an asynchronous reset input (MR) and an active-low enable input (EN).
Features:
4-bit binary counter
Multiplexed 7-segment display driver
Maximum operating voltage of 5V
Asynchronous reset input (MR)
Active-low enable input (EN)
Applications:
