LB1291

Ordering number:ENN1044C Monolithic Digital IC LB1291 8-Channel Driver Array Overview The LB1291 has been designed for interfacing between low level digital devices and fluorescent display tubes. Its 8channel independent Darlington output stage is used for digit or segment drivers. Also, with pull-down equivalent resistors, no externally connected resistors are required for ghost prevention. When the input voltage is at a high level, the output gets activated.
