The SN74ABT240AN is a flexible, low-skew, and high-performance logic buffer manufactured by Texas Instruments. It is part of the Advanced Buffer Technology (ABT) logic family, specifically falling under the logic buffers, drivers, receivers, and transceivers classification. This device contains a 3-state output which allows for data to be transferred between two buses in a multiple device configuration.

The SN74ABT240AN\'s application lies in providing a low-skew, high-performance, low-power solution to drive low voltage loads, transmit medium speed data bus signals, and receive TTL/LVCMOS signals. This device can be used for a number of applications such as providing address and data buffers for memories, programmable frequency dividers, output drivers for DTL, TTL, and CMOS logic, or providing a full-time enable/disable input to permit or inhibit data flow.

The SN74ABT240AN contains eight independent, non-inverting buffers with 3-state outputs designed to be used in bus oriented systems. The outputs can be enabled or disabled by a logic level at the enable inputs. When disabled, the output is high impedance, allowing for an easy connection to other devices. The input of the buffers have an input clamp diode which limits the differential voltage to approximately 0.3V to minimize the possibility of latchup. The device is designed to drive 2.3V to 5.5V load with 0 to 5.5V VCC supply. This device further operates over a wide temperature range with Its useful temperature range being between -40°C and +85°C.

At the core of the SN74ABT240AN is its advanced logic and buffer technology which it operates upon. This device is designed to drive 355 Ohm and 3K Ohm loads up to 3MHz edge rates with up to 5 Mbps data rates while offering superior drive load switching performance. The SN74ABT240AN operates using a bipolar CMOS (BiCMOS) process that combines the low power consumption capabilities of MOS technologies with small propagation delays associated with bipolar circuits. This device further contains the advantages of advanced biCMOS logic, such as high output drive, low quiescent device power, and biCmos compatibility. All this allows for the SN74ABT240AN to offer symmetrical, high-drive performance with superior propagation delays and noise immunity.

The SN74ABT240AN is a device whose application spans a wide range of uses. From providing address and data buffers for memories to providing output drivers for DTL, TTL, and CMOS logic the SN74ABT240AN can do it all. This coupled with its advanced logic and buffer technology, make it a versatile and low power consuming device that is ideal for multiple uses.
