Overview

The ISL7457SRH is a radiation hardened, SEE hardened, high-speed, non-inverting, quad CMOS driver. It is capable of running at clock rates up to 40MHz and features 2A typical peak drive capability and a nominal ON-resistance of just 3.5Ω. The ISL7457SRH is ideal for driving highly capacitive loads, such as storage and vertical clocks in CCD applications. It is also well suited to level-shifting and clock-driving applications. Each output of the ISL7457SRH can be switched to either the high (VH) or low (VL) supply pins, depending on the related input pin. The inputs are compatible with both 3.3V and 5V CMOS 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 that disable the driver during power-down. The ISL7457SRH also features very fast rise and fall times, which are typically matched to within 1ns. The propagation delay is also matched between rising and falling edges to typically within 1.5ns. The ISL7457SRH is available in a 16 Ld ceramic flatpack package and specified for operation across the full -55 °C to +125 °C ambient temperature range.
