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. 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.  
Features  
• Clocking speeds up to 40MHz  
• 4 channels  
• 12ns t /t at 1000pF C  
R F  
LOAD  
• 1ns rise and fall time match  
• 1.5ns prop delay match  
The EL7457 is capable of running from single or dual power  
supplies while using ground referenced inputs. Each output  
• Low quiescent current - <1mA  
can be switched to either the high (V ) or low (V ) supply  
H
L
• Fast output enable function - 12ns  
• Wide output voltage range  
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.  
• 8V V -5V  
L
• -2V V 16.5V  
H
• 2A peak drive  
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.  
• 3on resistance  
• Input level shifters  
• TTL/CMOS input-compatible  
• Pb-free (RoHS compliant)  
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.
