Description: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.
