description

The SN65512B and SN75512B are monolithic BIDFET

integrated circuits designed to drive a dot matrix or segmented vacuum fluorescent display.

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

The device consists of a 12-bit shift register, 12latches, 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.

The SN65512B is characterized for operation from -40°C to 85°C. The SN75512B is characterized for operation from 0°C to 70°C.
