RD74VT1G126
Bus Buffer Gate with 3-state Output / Dual Supply Voltage Translator
REJ03D0517-0100 Rev.1.00 Jun. 01, 2005
Description
The RD74VT1G126 has a bus buffer gate with 3-state output in a 6 pin package. Output is disabled when the associated output enable (OE) input is low. To ensure the high impedance state during power up or power down, OE should be connected to GND through a pull-down resistor; the minimum value of the resistor is determined by the current sourcing capability of the driver. The input is designed to track VCCIN, which accepts voltages from 1.2V to 3.6V, and the output is designed to track VCCOUT, which operates at 1.2V to 3.6V. Low voltage and high-speed operation is suitable for the battery powered products (e.g., notebook computers), and the low power consumption extends the battery life.
Features
* This product function as level shift that change VCCIN input level to VCCOUT output level by providing different supply voltage to VCCIN and VCCOUT. * The basic gate function is lined up as Renesas uni logic series. * Supplied on emboss taping for high-speed automatic mounting. * Supply voltage range: VCCIN = 1.2V to 3.6 V VCCOUT = 1.2 V to 3.6 V 40 Operating temperature range: -40 to +85C * All inputs VIH (Max.) = 3.6 V (@VCCIN = 0 V to 3.6 V) Outputs VO (Max.) = 3.6 V (@VCCOUT = 0 V) 2 * Output current 2 mA (@VCCOUT = 1.2 V) 4 4 mA (@VCCOUT = 1.4 V to 1.6 V) 6 6 mA (@VCCOUT = 1.65 V to 1.95 V) 18 mA (@VCCOUT = 2.3 V to 2.7 V) 24 mA (@VCCOUT = 3.0 V to 3.6 V) 24 * Ordering Information

Power-up Considerations
Level-translation devices offer an opportunity for successful mixed-voltage signal design. A proper power-up sequence always should be followed to avoid excessive supply current, bus contention, oscillations, or other anomalies caused by improperly biased device pins. Take these precautions to guard against such power-up problems. 1. Connect ground before any supply voltage is applied. 2. Next, power up the control side of the device. (Power up of VCCIN is first. Next power up is VCCOUT) 3. Tie OE to VCCIN with a pull-up resistor so that it ramps with VCCIN.
