Speedy optocoupler takes little to drive
A new high-isolation logic gate optocoupler offers high speed at low input drive current for industrial applications.
The FOD2200 is a low input current logic gate optocoupler that provides industry-leading high isolation voltage (5kV RMS) over a wide power supply voltage range The high common mode rejection (CMR) of 1kV/us and hysteresis output allows the FOD2200 to deliver optimum performance for high-speed applications in noisy industrial environments

Dual-output buffer for DDR SDRAM modules
Fairchild Semiconductor has introduced a dual-output registered buffer for 184-pin, 2.5V PC200/PC266, 72bit-wide registered double data rate (DDR) SDRAM modules.
Bus hold makes logic more predictable
Fairchild Semiconductor has made a number of additions to its LCX family, the logic industry standard for 3.3V applications.
The device's low IF (1.6mA, minimum) and wide VCC range (4.5-20V) not only lowers power consumption but makes it compatible with TTL, LSTTL and CMOS logic.
Other noteworthy features include electrical and switching characteristics guaranteed over a 0 to 85C range and a maximum propagation delay of 300ns.
The three-state output of the FOD2200 reduces additional circuit board components by eliminating the need for a pull-up resistor.
In high noise applications, the FOD2200 is especially effective for isolating high-speed logic interfaces and for buffering input and output lines.
This DIP-8 package is available in three leadform options for either through-hole or surface-mount applications.
"With its three state output detector and hysteresis circuitry, the FOD2200 allows the designer to drive data buses directly and eliminates the possibilities for output signal chatter", said Krish Ramdass, Strategic Marketing Manager for Fairchild's Optocoupler Group.
"The introduction of the FOD2200 further strengthens Fairchild's portfolio of high performance optocouplers designed for the industrial market segment".
