DESCRIPTION:

The LS7183N and LS7184N are CMOS quadrature clock converters. Quadrature clocks derived from optical or magnetic encoders, when applied to the A and B inputs of the LS7183N / LS7184N, are converted to strings of Up Clocks and Down Clocks (LS7183N) or to a Clock and an Up/Down direction control (LS7184N). These outputs can be interfaced directly with standard Up/Down counters for direction and position sensing of the encoder.

FEATURES:

• x1, x2 and x4 resolution

• Programmable output pulse width (200ns to 140µs)

• Excellent regulation of output pulse width

• TTL and low voltage CMOS compatible I/Os

• +3V to +12V operation (VDD- VSS)

• LS7183N,LS7184N (DIP) LS7183N-S, LS7184N-S(SOIC)
