ISL7457SRH FN6874
Rev.3.00
Jul 28, 2017 Radiation Hardened, SEE Hardened, Non-Inverting, Quad CMOS Driver 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 3.5О©. 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. Features 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. SEE hardness Electrically screened to SMD 5962-08230 QML qualified per MIL-PRF-38535 requirements Full mil-temp range operation: TA = -55В°C to +125В°C Radiation hardness TID [50-300 rad(Si)/s]: 10krad(Si) minimum LET (SEL and SEB Immunity): 40MeV/mg/cm2
minimum LET [SET = пЃ„VOUT < 15V, пЃ„t < 500ns]:
40MeV/mg/cm2 4 channels 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. Clocking speeds up to 40MHz The ISL7457SRH is available in a 16 Ld ceramic
flatpack package and specified for operation across the …
