Pericom Semiconductor PI74ALVCH16244A
PI74ALVCH16244 is an non-inverting 16-bit buffer/driver designed for low-voltage 2.3V to 3.6V VCC operation. The buffer/driver 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.| Part No. | PI74ALVCH16244A |

● Designed for low-voltage operation VCC = 2.3V to 3.6V Hysteresis on all inputs Typical VOLP (Output Ground Bounce) < 0.8V at VCC = 3.3V, TA = 25°C Typical VOHV (Output VOH Undershoot) < 2.0V at VCC = 3.3V, TA = 25°C Bus Hold retains last active bus state during 3-State, eliminating the need for external pullup resistors Industrial operation at –40°C to +85°C Packaging: – 48-pin 240-mil wide plastic TSSOP (A)
DESCRIPTION
Pericom Semiconductor’s It provides non-inverting 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 in which the minimum value is determined by the current-sinking capability of the driver. The PI74ALVCH16244 has “Bus Hold” which retains the data input’s last state whenever the data input goes to high-impedance preventing “floating” inputs and eliminating the need for pullup/ down resistors.
