A 10-bit data word is serially loaded into the shift
register on the positive-going transitions of the
clock. Parallel data is transferred to the output
buffers through a 10-bit D-type latch while LATCH
ENABLE is high and is latched when LATCH
ENABLE is low. When BLANKING is high, all
outputs are low.

Q4
Outputs are totem-pole structures formed by npn
emitter-follower and double-diffused MOS
(DMOS) transistors with output voltage ratings of
70 V and 40-mA source-current capability. All
inputs are compatible with CMOS and TTL levels,
but each requires the addition of a pullup resistor
NC–No internal connection
to V
when driven by TTL logic.
CC1
The TL4810B is characterized for operation from
0°C to 70°C. The TL4810BI is characterized for
operation from –40°C to 85°C.
†BIDFET – Bipolar, double-diffused, N-channel and P-channel MOS transistors on same chip. This is a patented process.
