HD74ALVCH162244 16-bit Buffers / Drivers with 3-state Outputs REJ03D0052-0300Z (Previous ADE-205-173A(Z)) Rev.3.00 Oct.02.2003 Description The HD74ALVCH162244 is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus oriented receivers and transmitters. The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. It provides true outputs and symmetrical active-low output-enable (OE) inputs. To ensure the high impedance state during power up or power down, OE 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. Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level. All outputs, which are designed to sink up to 12 mA, include 26 Ω resistors to reduce overshoot and undershoot. VCC = 2.3 V to 3.6 V Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta ...
