Description
The HCPL4503M optocoupler consists of an AlGaAs LED
optically coupled to a high speed photodetector transistor.
A separate connection for the bias of the photodiode improves
the speed by several orders of magnitude over conventional
phototransistor optocouplers by reducing the base-collector
capacitance of the input transistor. The base of the phototrans-
istor is not bonded out to a pin for improved noise immunity.
An internal noise shield provides superior common mode
rejection of 15kV/µs minimum.
Applications
■
Line receivers
■
Pulse transformer replacement
■
Output interface to CMOS-LSTTL-TTL
■
Wide bandwidth analog coupling

Notes
1. Current Transfer Ratio is defined as a ratio of output collector current, I
O
, to the forward LED input current, I
F
, times 100%.
2. The 1.9 k
Ω
load represents 1 TTL unit load of 1.6 mA and 5.6 k
Ω
pull-up resistor.
3. Common mode transient immunity in logic high level is the maximum tolerable (positive) dV
cm
/dt on the leading edge of the com-
mon mode pulse signal V
CM
, to assure that the output will remain in a logic high state (i.e., V
O
>2.0 V). Common mode transient
immunity in logic low level is the maximum tolerable (negative) dV
cm
/dt on the trailing edge of the common mode pulse signal,
V
CM
, to assure that the output will remain in a logic low state (i.e., V
O
<0.8 V).
4. Device is considered a two terminal device: Pins 1, 2, 3 and 4 are shorted together and Pins 5, 6, 7 and 8 are shorted together.
