Description

A buffer/line driver is an electronic device that is designed to transfer digital signals between different components or systems.

This octal buffer and line driver is designed to have the performance of the DM74ALS240A, DM74ALS540AN series and, at the same time, offer a pinout with inputs and outputs on opposite sides of the package. This arrangement greatly enhances printed circuit board layout. The 3-STATE control gate is a 2-input NOR such that if either G1 or G2 is HIGH, all eight outputs are in the high impedance state.

The “buffer” part refers to the ability of the device to store a temporary copy of the digital signals. Buffers are used to ensure that signals are not lost or corrupted during transfer, and they can also help to match the impedance between the source and the destination.

The “line driver” part refers to the ability of the device to boost the strength of the digital signals to ensure they can travel long distances without losing integrity. This is particularly important in applications where the signals need to be transmitted over long cables or wires.

Features

1. Advanced oxide-isolated, ion-implanted Schottky TTL process

2.  Switching performance is guaranteed over full temperature and VCC supply range

3.  Data flow-thru pinout (All inputs on opposite side from outputs)

4. P-N-P inputs reduce DC loading

Part Number: 74ALVCH16244

Function: 2.5V/3.3V 16-bit Buffer / Line Driver (3-State)

Package: SSOP, TSSOP 48 Pin type

Description

The 74ALVCH16244 is a 16-bit non-inverting buffer/line driver with 3-state outputs. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. The 3-state outputs are controlled by he output enable inputs 1OE, 2OE, 3OE and 4OE. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state.

The 74ALVCH16244 has active bus hold circuitry which is provided to hold unused or floating data inputs at a valid ogic level. This feature eliminates the need for external pull-up or pull-down resistors. The 74ALVC16244 has 5 V tolerant inputs.

A 16-bit buffer/line driver is an electronic device that is designed to transfer digital signals between different components or systems.

The “16-bit” part refers to the width of the data bus, which means that the buffer/line driver can handle 16 bits of digital information at a time. The data bus is the path that carries the digital signals between components or systems, and the width of the bus determines how many bits can be transferred simultaneously.

In summary, a 16-bit buffer/line driver is a device that can store and boost digital signals of up to 16 bits in width, ensuring that they can be transferred between different components or systems without loss or corruption over long distances.

Features

1. Wide supply voltage range of 1.2V to 3.6V

2. Complies with JEDEC standard no. 8-1A

3. CMOS low power consumption

4. MULTIBYTETM flow-through standard pin-out architecture

5. Low inductance multiple VCC and GND pins for minimum noise and ground bounce

6. Direct interface with TTL levels
