Dual Rank 8-Bit TRI-STATE Shift Register
General Description
These circuits are TRI-STATE edge-triggered 8-bit I O reg-
isters in parallel with 8-bit serial shift registers which are
capable of operating in any of the following modes parallel
load from I O pins to register ‘‘A’’ parallel transfer down
from register ‘‘A’’ to serial shift register ‘‘B’’ parallel transfer
up from shift register ‘‘B’’ to register ‘‘A’’ serial shift of regis-
ter ‘‘B’’ or exchange data between register ‘‘A’’ and shift
register ‘‘B’’ Since the registers are edge-triggered by the
positive transition of the clock the control lines which deter-
mine the mode or operation are completely independent of
the logic level applied to the clock Designed for bus-orient-
ed systems these circuits have their TRI-STATE inputs and
outputs on the same pins
Features
Y Registers are edge-triggered by the positive transition
of the clock
Y All inputs are PNP transistors
Y Input disable dominates over output disable
Y Output high impedance state does not impede any oth-
er mode of operation
Y 8-bit I O pins are TRI-STATE buffers
Y Typical shift frequency is 36 MHz
Y Typical power dissipation is 305 mW
Y All control inputs are active when in an ‘‘L’’ logic state
Y Devices can be cascaded into N-bit word
