MC74LV594A Datasheet, PDF (1/12 Pages) ON Semiconductor – 8-Bit Shift Register
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
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
