TOSHIBA BiâCMOS INTEGRATED CIRCUIT SILICON MONOLITHIC
TB62709NG,TB62709FG
7âSEGMENT DRIVERS WITH BUILTâIN DECODERS
(COMMON ANODE CAPABILITY, MAXIMUM 4âDIGIT CONTROL)
The TB62709NG and TB62709FG are multifunctional, compact,
7âsegment LED display drivers.
These ICs can directly drive 7âsegment displays and individual
LEDs, and can control either a 4âdigit display with decimal
points, or 32 individual LEDs.
These ICs can also be used with commonâanode displays. Their
outputs are constant current, the ampere levels at which are set
using an external resistor.
A synchronous serial port connects the IC to the CPU.
The different modes of control provided by this device including
Duty Control Register Set, Digit Set, Decode Set and Standby Set,
are all based on every 16âbit of serial data.
This devices are a product for the Pb free(Sn-Ag).
