8-BIT SERIAL-IN SHIFT
REGISTER WITH LATCHED
3-STATE PARALLEL OUTPUTS，
PROVIDING SERIAL OUTPUT
DESCRIPTION
The UTC 74HC595A contains an 8-bit register with
asynchronous reset input and an 8-bit latch with output. The Serial
Data Input (A) will shift into the internal shift register during every
LOW-to-HIGH transition on the Shift Clock. The latch will latch the
8-bit data from the shift register during the LOW-to-HIGH transition
on the Latch Clock. The shift register also provides a serial output.
FEATURES
* Operation Voltage Range:2~6V
* High Noise Immunity
* Output Compatibility with CMOS and TTL
* Specified from -40~+125°C
* Halogen Free

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are
observed.
