General Description
The EL7457C is an ultra-high speed, non-inverting quad CMOS
driver. It is capable of running at clock rates up to 40MHz and features
2A peak drive capability and a nominal on-resistance of just 3Ω. The
EL7457C is ideal for driving highly capacitive loads, such as storage
and vertical clocks in CCD applications. It is also well suited to ATE
pin driving, level-shifting and clock-driving applications.
The EL7457C is capable of running from single or dual power sup-
plies while using ground referenced inputs. Each output can be
switched to either the high (VH) or low (VL) supply pins, depending
on the related input pin. The inputs are compatible with both 3V and
5V CMOS and TTL 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 EL7457C also features very fast rise and fall times which are
matched to within 1ns. The propagation delay is also matched between
rising and falling edges to within 2ns.
The EL7457C is available in both the 16-Pin QSOP and 16-Pin SOIC
packages. It is specified for operation over the -40°C to +85°C temper-
ature range.
