8-bit Shift Registers with 3-state Outputs
REJ03D0335–0200Z
(Previous ADE-205-281 (Z))
Rev.2.00
Jun. 28, 2004
Description
This device each contains an 8-bit serial-in, parallel-out shift registers 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 register and the storage
register. The shift register has a direct-overriding clear, serial input, and serial output pins for cascading.
Both the shift register and the storage register clocks are positive-edge triggered. If the user wishes to connect both
clocks together, the shift register state will always be one clock pulse ahead of the storage register. Low-voltage and
high-speed operation is suitable for the battery-powered products (e.g., notebook computers), and the low-power
consumption extends the battery life.

Notes: The absolute maximum ratings are values, which must not individually be exceeded, and furthermore, no two of
which may be realized at the same time.
1. The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are
observed.
2. This value is limited to 5.5 V maximum.
3. The maximum package power dissipation was calculated using a junction temperature of 150°C.
