TI SN75554FN

The SN65553, SN65554, SN75553, and SN75554 are monolithic BIDFET integrated circuits designed to drive the column electrodes of an electroluminescent display. The SN65554 and SN75554 output sequence is reversed from the SN65553 and SN75553 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. 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 SN65553 and SN65554 are characterized for operation from -40°C to 85°C. The SN75553 and SN75554 are characterized for operation from 0°C to 70°C.
