MC74LV594A 8-Bit Shift Register with Output Register The MC74LV594A is an 8bit shift register designed for 2 V to 6.0 V V operation. The device contain an 8bit serialin, CC parallelout shift register that feeds an 8bit Dtype storage register. www.onsemi.com Separate clocks (RCLK, SRCLK) and direct overriding clear (RCLR, SRCLR) inputs are provided on the shift and storage registers. A serial MARKING output (Q ) is provided for cascading purposes. H DIAGRAMS The shiftregister (SRCLK) and storageregister (RCLK) clocks 16 are positiveedge triggered. If the clocks are tied together, the shift SOIC16 LV594AG register always is one clock pulse ahead of the storage register.
