42-DL221
OPTICAL FIBER TRANSMITTING IC
GENERAL DESCRIPTION
42-DL221 is a driver IC designed for the application of high-speed optical fiber
transmission. It integrates the LED driver with constant current output to reduce the complexity
and the cost of the transmission module. 42-DL221 can transmit with the speed up to 25Mb/s.
42-DL221 are fabricated by using CMOS technology with low power consumption purpose.
FEATURES
1. TTL interface compatible
2. High speed (up to 25Mb/s)
3. Uniform output waveform
4. Constant current output
5. Low power consumption
6. Wide range for Supply Voltage (2.7V-5.5V)

HANDLING RECOMMENDATION FOR STATIC ELECTRICITY PROTECTION
(1) Avoid any circumstance that produce static electricity, e.g. rubbing against plastic, during
moving, storing and processing 42-DL221.
(2) Process 42-DL221 in a clean room with proper temperature and humidity.
(3) Ground all working machines and workers wear anti-electrostatic ring to ground during
processing.
(4) Avoid contact 42-DL221 with bare hands .If unavoided, wear anti-electrostatic ring and use
anti-electrostatic tool to pick it up.
GUARANTED TEMPERATURE AND RETENTION CYCLE
