logic symbol  
All device inputs are diode-clamped pnp inputs  
and assume a high logic level when open  
circuited. The nominal input threshold voltage is  
1.5 V. Outputs are totem-pole structures formed  
by an npn emitter-follower and double-diffused  
MOS (DMOS) transistors.

LATCH ENABLE  
STROBE  
The device consists of a 12-bit shift register,  
12 latches, and 12 output AND gates. Serial data  
is entered into the shift register on the low-to-high  
transition of CLOCK. When high, LATCH ENABLE  
transfers the shift register contents to the outputs  
of the 12 latches. The active-low STROBE input  
enables all Q outputs. Serial data output from the  
shift register can be used to cascade shift  
registers. This output is not affected by LATCH  
ENABLE or STROBE.
