TH7426A/27A
NEAR INFRARED InGaAs LINEAR IMAGE SENSOR
300 PIXELS
DESCRIPTION
These devices are based on a 300 InGaAs photodiode li-
near array, with a 26µm pitch, using an in line pixel layout or
a staggered pixel layout.
Two 150:1 CCD multiplexor chips, offering memory and de-
layed readout capability, are hybridized on both sides of the
photodiode array so as to build a complete module.
Specially designed to allow an accurate butting, those mo-
dules could be tied together on request so as to provide an
array extension with only one dead pixel at the splice.
These devices are also available in a full CMOS interface
version :
TH74KA26A/TH74KA27A or TH74KB26A/TH74KB27A.

PIN DESCRIPTION
Odd and Even channels are fully independent, therefore same pin function will be found on odd and even sides.
F
PL
This is the preload injection stage electrical input. Each
Φ
PL
pulse down overfills preload storage capacitance with
electrons.
Φ
PL
is connected to a diode cathode which anode is internally tied to Vss.
VGL1
This is the preload stage skimming gate. Its bias determines the voltage up to which preload storage capacitance
will be biased. Thus it drives preload level.
VGL2
This is the storage capacitance grid bias. It determines the bottom voltage of preload storing well, while V
GL1
deter-
mines its top level. Preload capacitance thus is charged up proportionately to (V
GL2
- V
GL1
) bias difference.
F
L1
F
L2
This is the main register storage grid clock. Charges are stored under
Φ
L1
when transfer is disabled (RE at low le-
vel).
F
L1
is also used for lateral transfers to input nodes.
This is the main register transfer grid clock.
Φ
L2
is used to isolate
F
L1
content during lateral transfers. The main re-
gister is beginning and ending with
F
L2
which therefore controls main register access and outputs.
F
L2
is gated by
RE input, it is internally pulled down when RE is low, preventing transfers, preload injection, read out and isolating
each
F
L1
well.
This is the “Read Enable” input. When high, it allows
Φ
L2
input connection to main register, when low, main register
corresponding grids are pulled down whatever
F
L2
input level is.
This input helps to serially read out two or more multiplexors with one single
F
L2
signal for all. Data are stored into
the main register as long as RE is low, thus read out can occur later on.
This is the lateral transfer grid command. Lateral transfer is allowed when
F
X
is at high level.
F
X
is common to all
input nodes, all photodiode information is collected at the same time.
This is the lateral input stage skimming grid bias. This grid determines photodiodes reset bias, always the same
from integration time to integration time. After photodiode reset (input node capacitance reset) extra charges leading
to overcrossing V
G1
level are skimmed back into
Φ
L1
main register wells.
This is the InGaAs photodiode common cathode bias. V
N
is available on odd and ev en side, however, both pins are
connected together, to photodiode substrate.
This is main register output grid bias. It is used to isolate read out capacitance from main register. It allows charges
to be read out when
Φ
L2
is at low level.
This is the read out capacitance reset bias. After each single read out, read out capacitance is cleared off (reset) to
V
DR
level, during
F
R
clock high state.
