Radiation Hardened, SEE Hardened, Non-Inverting,
Quad CMOS Driver
ISL7457SRH
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 by the Defense Supply Center in
Columbus (DSCC). The SMD numbers listed here
must be used when ordering.
