MC74LV594A
8-Bit Shift Register with Output Register
The MC74LV594A is an 8−bit shift register designed for 2 V to 6.0 V VCC operation. The device contain an 8−bit serial−in, parallel−out shift register that feeds an 8−bit D−type storage register. Separate clocks (RCLK, SRCLK) and direct overriding clear (RCLR, SRCLR) inputs are provided on the shift and storage registers. A serial output (QH’) is provided for cascading purposes.
The shift−register (SRCLK) and storage−register (RCLK) clocks ar.

8-Bit Shift Register with Output Register
The MC74LV594A is an 8−bit shift register designed for 2 V to 6.0 V VCC operation. The device contain an 8−bit serial−in, parallel−out shift register that feeds an 8−bit D−type storage register. Separate clocks (RCLK, SRCLK) and direct overriding clear (RCLR, SRCLR) inputs are provided on the shift and storage registers. A serial output (QH’) is provided for cascading purposes.
The shift−register (SRCLK) and storage−register (RCLK) clocks are positive−edge triggered. If the clocks are tied together, the shift register always is one clock pulse ahead of the storage register.
Features
• 2.0 V to 6.0 V VCC Operation • Low Input Current: 1.0 mA • Max tpd of 6.5 ns at 5 V • Typical VOLP (Output Ground Bounce) < 0.8 V
