Feb 24, 11, 2, B When a LOW level is applied to the blanking input forced condition all segment outputs go to a LOW level regardless of the state of any other input condition. The CO signal is a symmetrical square- wave at one-tenth of the CLK input daatasheet, and is useful in cascading B counters. Full text of ” IC Datasheet: Feb 17, 4, 1, Not more than one output should be shorted at a time, nor for more than 1 second.

The opening episode of this special feature explained the basic operating and usage principles of seven-segment alphanumeric displays. Your name or email address: Feb 1, 9 0. Dec 6, 8. Each segemnt of the display has associated with it a Boolean equation that determines weather the segment is on or off. The B is very easy to use, and has only three input control terminals; of these, the not-LT datwsheet 3 pin is normally tied high, but turns on all seven segments of the display when pulled low.
