Product specification
NE587
DESCRIPTION
The NE587 is a latch/decoder/driver for 7-segment common anode
LED displays. The NE587 has a programmable current output up to
50mA which is essentially independent of output voltage, power
supply voltage, and temperature. The data (BCD) inputs and LE
(latch enable) input are low-loading so that they are compatible with
any data bus system. The 7-segment decoding is implemented with
a ROM so that alternative fonts can be made available.
FEATURES
• Latched BCD inputs
• Low loading bus-compatible inputs
• Ripple-blanking on leading- and/or trailing-edge zeros
APPLICATIONS
• Digital panel motors
• Measuring instruments
• Test equipment
• Digital clocks
• Digital bus monitoring
