SN75518

Overview
ą • Each Device Drives 32 Lines • 60-V Output Voltage Swing Capability • 25-mA Output Source Current Capability • High-Speed Serially Shifted Data Input • Latches on All Driver Outputs description The SN65518 and SN75518 are monolithic BIDFET† integrated circuits designed to drive a dot matrix or segmented vacuum fluorescent display.
Each device consists 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.
While LATCH ENABLE is high, parallel data is transferred to the output buffers through a 32-bit latch.
Data present in the latch during the high-to-low transition of LATCH ENABLE is latched.
