3 Description

The SN74LV8T596-Q1 device contains an 8-bit,

serial-in, parallel-out shift register that feeds an 8-

bit D-type storage register. All inputs include Schmitttriggers,

eliminating any erroneous data outputs due

to slow-edged or noisy input signals. The storage

register has parallel open-drain 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 outputs are in a high impedance

state. The operation of the OE input does not impact

the internal register data

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.
