SN74HC594N, Регистр сдвига, Последовательный в Параллельный, 1 Элемент [DIP-16]

The SN74HC594N is a 8-bit Shift Register with output registers. It contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. Separate clocks and direct overriding clear (RCLR, SRCLR) inputs are provided on both the shift and storage registers. A serial (QH’) output is provided for cascading purposes. Both the shift register (SRCLK) and storage register (RCLK) clocks are positive edge triggered. If both clocks are connected together, the shift register always is one count pulse ahead of the storage register. The parallel (QA — QH) outputs have high-current capability. QH is a standard output.

• High-current outputs can drive up to 15 LSTTL loads
• Typical tpd = 15ns
• Independent direct overriding clears on shift and storage registers
• Independent clocks for both shift and storage registers
• 80µA Maximum low power consumption
• ±6mA Output drive at 5V
• 1µA Maximum low input current
