High Speed Drivers Intersil’s high speed drivers provide a range of products that enable digital devices to drive high capacitive loads. These devices can be viewed as level translators. They enable low voltage / low current signals (FPGA, Microprocessor) to interface to a wide range of voltage or current requirements. Essentially precision drivers enable digital control / communication with “non-digital devices” or digital devices operating with different voltage thresholds. Voltage / current thresholds designated to be a digital 1 or digital 0. Most of the product family is unidirectional. They enable a low level / current signal to control an external device such as a relay. These devices may also be used for “Clock” distribution and work as buffers between a frequency source and multiple devices.

Quad Driver
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 nominalon-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
