Integrated Circuit
Seven–Segment Latch/Decoder/Driver for Common Anode LED’s
Description:
The NTE 8374 is a 7–segment decoder driver in a 16–Lead DIP type package incorporating input
latches and output circuits to directly drive common anode LED displays.
Features:
High speed input latches for data storage
15mA constant current sink capability to directly drive common anode led displays
Increases incandescent display life
Active low latch enable for easy interface with MSI circuits
Data input loading essentially zero when latch disabled
Automatic ripple blanking for suppression of leading and/or trailing–edge zeroes.
