TC62D749CFG
16-Output Constant Current LED Driver (Output switching high-speed version)
The TC62D749CFG is a constant-current driver for LED and
LED display lighting applications.
The output current from each of the 16 outputs is
programmable via a single external resistor.
The TC62D749CFG contains a 16-channel shift register, a
16-channel latch, a 16-channel AND gate and a 16-channel
constant-current output.
Fabricated with a CMOS process, the TC62D749CFG allows
high-speed data transfer.
It operates with a 3.3- or 5-V power supply.
SSOP24-P-300-1.00B
Weight: 0.29 g (Typ.)
Features
Supply voltages
: VDD = 3.0 V to 5.5 V
16-output built-in
Output current setup range
: IOUT = 1.5 to 90 mA
Constant current output accuracy (@ REXT = 1.2 k, VOUT = 1.0 V, VDD = 3.3 V, 5.0 V)
: S rankbetween outputs ± 1.5 % (max)
: S rankbetween devices: ± 1.5 % (max)
: N rankbetween outputs ± 2.5 % (max)
: N rankbetween devices: ± 2.5 % (max)
Output voltage
: VOUT = 17 V (max)
High-speed output switching
: twOE = 25 ns (min), tor = 10ns (typ.), tof = 10ns (typ.)
There is TC62D748 as an output switching standard-speed version of this product.
I/O interface
: CMOS interfaces (Schmitt trigger input)
Data transfer frequency
: fSCK = 25 MHz (max)
Operation temperature range
: Topr = 40 to 85 °C
Power-on-reset function built-in. (When the power supply is turned on, internal data is reset)
Package
: SSOP24-P-300-1.00B
For detailed part naming conventions, contact your local Toshiba sales representative or distributor.
When the LED driver of high-speed output switching is used, back EMF may occur at the time of output OFF, and
output terminal voltage may rise. Please be careful. It is necessary to reduce inductance to prevent the back EMF. It
is possible to reduce inductance of a substrate by making the power supply for LED wiring shorter and wider
designing the layout pattern.

The latch circuit is a leveled-latch circuit. Please exercise precaution as it is not triggered-latch circuit.
Keep the SLAT pin is set to “L” to enable the latch circuit to hold data. In addition, when the SLAT
pin is set to “H” the latch circuit does not hold data. The data will instead pass onto output.
When the OE pin is set to “L” the OUT0 to OUT15 output pins will go ON and OFF in response to
the data. In addition, when the OE pin is set to “H” all the output pins will be forced OFF regardless of
the data.
This product can use 3.3V and 5.0V power supply, but power supply and input (SCK/SIN/ SLAT / OE )
must use same voltage.
