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:
D High speed input latches for data storage
D 15mA constant current sink capability to directly drive common anode led displays
D Increases incandescent display life
D Active low latch enable for easy interface with MSI circuits
D Data input loading essentially zero when latch disabled
D Automatic ripple blanking for suppression of leading and/or trailing–edge zeroes.
