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

NOTES:
NE587 Programming:
The NE587 output current can be programmed, provided a program resistor, RP, be connected between IP (Pin 8) and Ground (Pin 9). The
voltage at IP (Pin 8) is constant (1.3V). Thus, a current through RP is IP 1.3V/RP, as shown in Figure 5. IO/IP is 20 in the 15 to 50mA output
current range.
