74ALVCHS162830
General description
The ALVCHS162830 address driver is designed for 2.3 V to 3.6 V VCC operation.
Diodes to VCC have been added on the inputs to clamp overshoot.
The bus hold feature retains the inputs? last state whenever the input bus goes to high impedance. This prevents floating inputs and eliminates the need for pull up or pull down resistors.
The outputs, which are designed to sink up to 12 mA, include equivalent 26 Ohm series resistors to reduce overshoot and undershoot.
To ensure the high-impedance state during power up or power down, the output-enable (OE) input should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The 74ALVCHS162830 is characterized for operation from -40 to +85 Cel.
Features
- Output ports have equivalent 26 Ohm series resistors, so no external resistors are required
- Diodes on inputs clamp overshoot
- ESD classification testing is done to JEDEC Standard JESD22. Protection exceeds 2000 V HBM per method A114.
- Latch-up testing is done to JEDEC Standard JESD78, which exceeds 100 mA.
- Bus hold on data inputs eliminates the need for external pullup/pulldown resistors
- Packaged in thin very small-outline package (TVSOP) - 0.4 mm pitch
- Optimized for use with PCK953 in SDRAM module applications
- Balanced +- 12 mA output drive
- Low noise, low skew
