Texas Instruments' SN74AUP1G125 bus buffer gates are a single line driver with a 3-state output. The output is disabled when the output-enable (OE) input is high. These devices have the input-disable feature, which allows floating input signals.
To ensure the high-impedance state during power up or power down, OE must be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
| Features |
|
|
- Available in the Texas Instruments NanoStar™ package
- Low static-power consumption (ICC = 0.9 µA max.)
- Low dynamic-power consumption (Cpd = 4 pF typ. at 3.3 V)
- Low input capacitance (CI = 1.5 pF typ.)
- Low noise - overshoot and undershoot < 10% of VCC
- Input-disable feature allows floating input conditions
|
|
- Ioff supports partial-power-down mode operation
- Input hysteresis allows slow input transition and better switching noise immunity at input
- Wide operating VCC range of 0.8 V to 3.6 V
- 3.6 V I/O tolerant to support mixed-mode signal operation
- tpd = 4.6 ns max. at 3.3 V
