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)

REQUIREMENTS FOR WAFER DELIVERY
Material： Silicon with P-Substrate
Diameter： 6 inches(≒15cm)
Thickness： 15 mils(≒375um)
Malfunctioned die：Marked with red ink or equivalent marking
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
(1) The device/wafer 42-DL221 should be stored in the nitrogenous chest. The conditions suggested
are as follows:
Temperature = 23±3℃
Relative Humidity = 50±10%
Minimum nitrogen inflow = 3 liters/minute
(2) If the device/wafer, 42-DL221 is incidentally exposed to the air, use it for manufacturing as soon
as possible.
(3) Under the storage environment specified in item (1), six-month safe storage period is
guaranteed.
