EL7457

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 3

Ω. 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

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.
