TI SN75555FN

SLDS031A – APRIL 1985 – REVISED APRIL 1993
High-Speed Serially-Shifted Data Input
Totem-Pole Outputs
Latches on All Driver Outputs
description
The SN65555, SN75555, SN65556, and
SN75556 are monolithic BIDFET† integrated
circuits designed to drive the column electrodes of
an electroluminescent display. The SN65556 and
SN75556 output sequence is reversed from the
SN65555 and SN75555 for ease in printed-circuitboard layout.
The devices consist of a 32-bit shift register, 32
latches, and 32 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 32 latches. When OUTPUT ENABLE is
high, all Q outputs are enabled. Data must be
loaded into the latches and OUTPUT ENABLE
must be high before supply voltage VCC2 is
ramped up.
Serial data output from the shift register can be
used to cascade shift registers. This output is not
affected by LATCH ENABLE or OUTPUT
ENABLE.
