Component qualification in accordance with JEDEC and industry
standards to ensure reliable operation over an extended
temperature range. This includes, but is not limited to, Highly
Accelerated Stress Test (HAST) or biased 85/85, temperature
cycle, autoclave or unbiased HAST, electromigration, bond
intermetallic life, and mold compound life. Such qualification
testing should not be viewed as justifying use of this component
beyond specified performance and environmental limits.

description/ordering information
The SN74LV595A is an 8-bit shift register designed for 2-V to 5.5-V V
CC
operation.
This device contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The
storage register has parallel 3-state outputs. Separate clocks are provided for both the shift and storage register.
The shift register has a direct overriding clear (SRCLR
) input, serial (SER) input, and a serial output for
cascading. When the output-enable (OE
) input is high, all outputs except Q
H
are in the high-impedance state.
Both the shift register clock (SRCLK) and storage register clock (RCLK) are positive-edge triggered. If both
clocks are connected together, the shift register always is one clock pulse ahead of the storage register.
To ensure the high-impedance state during power up or power down, OE
should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The device is fully specified for partial-power-down applications using I
off
. The I
off
circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
