description
The ’LV594A devices are 8-bit shift registers
designed for 2-V to 5.5-V V_CC operation.
NC – No internal connection
These devices 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
(Q_H′) 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.
The SN54LV594A is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74LV594A is characterized for operation from –40°C to 85°C.
