74ALVCH162827

20-bit buffer/line driver; non-inverting; with 30 Ohm termination resistors; 3-state

The 74ALVCH162827 20-bit buffers provide high performance bus interface buffering for wide data/address paths or buses carrying parity. They have NAND output enables (nOE1 and nOE2) for maximum control flexibility.

The 74ALVCH162827 is designed with 30 Ω series resisters in both the pull-up and pull-down output structures. This design reduces line noise in applications such as memory address drivers, clock drivers and bus receivers/transmitters.

To ensure the high impedance state during power up or power down, nOEn should be tied to V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking/current-sourcing capability of the driver.

The 74ALVCH162827 has active bus hold circuitry which is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors.
