CMOS technology. These high-speed, low-power 18-bit registered transceivers combine D-type latches D-type Common features: flip-flops allow data flow transparent, latched clocked MICRON CMOS Technology modes. Data flow each direction controlled output- High-speed, low-power CMOS replacement enable (OEAB OEBA), latch enable (LEAB LEBA) functions clock (CLKAB CLKBA) inputs. A-to-B data flow, Typical tSK(o) (Output Skew) 250ps device operates transparent mode when LEAB HIGH. input output leakage (max.) When LEAB LOW, data latched CLKAB held 2000V MIL-STD-883, Method 3015; HIGH logic level. LEAB LOW, data 200V using machine model 200pF, stored latch/flip-flop LOW-to-HIGH transition Packages include pitch SSOP, 19.6 pitch TSSOP, 15.7 pitch TVSOP pitch Cerpack CLKAB. OEAB output enable port. Data flow from port port similar requires using OEBA, Extended commercial range -40°C +85°C LEBA CLKBA. Flow-through organization signal pins Features FCT16501AT/CT/ET: simplifies layout. inputs designed with hysteresis High drive outputs (-32mA IOH, 64mA IOL) improved noise margin. Power disable outputs permit "live insertion" FCT16501AT/CT/ET ideally suited driving Typical VOLP (Output Ground Bounce) 1.0V high-capacitance loads low-impedance backplanes. 25°C output buffers designed with power disable capability Features FCT162501AT/CT/ET: allow "live insertion" boards when used backplane Balanced Output Drivers: ±24mA (commercial), drivers. ±16mA (military) FCT162501AT/CT/ET have balanced output drive Reduced system switching noise with current limiting resistors. This offers ground bounce, Typical VOLP (Output Ground Bounce) 0.6V minimal undershoot, controlled output fall times-reducing 5V,TA 25°C need external series terminating resistors.

FCT162H501AT/CT/ET have "Bus Hold" which reDESCRIPTION: tains input's last state whenever input goes high FCT16501AT/CT/ET FCT162501AT/CT/ET impedance. This prevents "floating" inputs eliminates registered transceivers built using advanced dual metal need pull-up/down resistors.
