FN6874.0
Radiation Hardened, SEE Hardened,
Non-Inverting, Quad CMOS Driver
The ISL7457SRH is a radiation hardened, SEE hardened,
high speed, non-inverting, quad CMOS driver. It is capable
of running at clock rates up to 40MHz and features 2A
typical peak drive capability and a nominal on-resistance of
just 3.5Ω. The ISL7457SRH is ideal for driving highly
capacitive loads, such as storage and vertical clocks in CCD
applications. It is also well suited to level-shifting and
clock-driving applications.
Each output of the ISL7457SRH can be switched to either
the high (V
H
) or low (V
L
) supply pins, depending on the
related input pin. The inputs are compatible with both 3.3V
and 5V CMOS logic. The output enable (OE) pin can be
used to put the outputs into a high-impedance state. This is
especially useful in CCD applications, where the driver
should be disabled during power down.
The ISL7457SRH also features very fast rise and fall times
which are typically matched to within 1ns. The propagation
delay is also matched between rising and falling edges to
typically within 1.5ns.
The ISL7457SRH is available in a 16 lead ceramic flatpack
package and specified for operation over the full -55°C to
+125°C ambient temperature range.
Specifications for Rad Hard QML devices are controlled
