description

The SN65555, SN75555, SN65556, and SN75556 are monolithic BIDFET^{^[dagger]} 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-circuit-board 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 V_CC2 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.

The SN65555 and SN65556 are characterized for operation from -40°C to 85°C. The SN75555 and SN75556 are characterized for operation from 0°C to 70°C.
