3 Description

The SN74LV8T595-Q1 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 (QH') for

cascading. When the output-enable (OE) input is high,

the storage register outputs are in a high-impedance

state. Internal register data and serial output (QH') are

not impacted by the operation of the OE input.

The input is designed with a reduced threshold circuit

to support up translation when the supply voltage

is larger than the input voltage. Additionally, the 5V

tolerant input pins enable down translation when the

input voltage is larger than the supply voltage. The

output level is always referenced to the supply voltage

(VCC) and supports 1.8V, 2.5V, 3.3V, and 5V CMOS

levels.
