40MHz Non-Inverting Quad CMOS Driver
The EL7457 is a 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 EL7457 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 EL7457 is capable of running from single or dual power
supplies 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 EL7457 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 EL7457 is available in 16-pin QSOP, 16-pin SO
(0.150"), and 16-pin QFN packages. All are specified for
operation over the full -40°C to +85°C temperature range.
