The EL7457 is a high speed, non-inverting, quad CMOS driver from Intersil. 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 quad CMOS driver from Intersil provides fast, non‑inverting outputs for high‑speed clocking and level‑shifting applications. It operates from single or dual supplies, supports TTL and CMOS logic levels, and includes an output‑enable pin for high‑impedance control.
Key features include up to 40 MHz clock rates, 2 A peak drive, low on‑resistance, fast rise/fall times, and a wide output voltage range from –2 V to 16.5 V. The device is offered in 16‑pin QSOP, SO, and QFN packages, with RoHS‑compliant, Pb‑free options.
