The SN65518 and SN75518 are monolithic

BIDFET integrated circuits designed to drive a

dot matrix or segmented vacuum fluorescent

display.

Q25

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. When STROBE is low, all Q

outputs are enabled. When STROBE is high, all Q

outputs are low.

Serial data output from the shift register may be

used to cascade additional devices. This output is

not affected by LATCH ENABLE or STROBE.
