HCPL4503M
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 phototransistor is
not bonded out to a pin for improved noise immunity.
An internal noise shield provides superior common mode rejection of 15kV/s minimum.
FEATURES
VISO = 5kV RMS is standard for all devices
High speed-1 MBit/s
Superior CMR, CM
H
= 50 kV/ms (typical); CM
L
= 30 kV/ms (typical)
No base connection for improved noise immunity
CTR guaranteed 0-70C
U.L. recognized (File # E90700, Vol 2)
VDE approval pending

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
load represents 1 TTL unit load of 1.6 mA and 5.6 k 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
common 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.
