The SN74ABTH25245DWG4 is a Logic - Buffers, Drivers, Receivers, Transceivers. This device is a high-speed TTL-compatible 8-bit transceiver that is based on the improved TTL (ABT) family of logic. This transceiver has two sets of three-state output controls (G1 and G2) that enable isolation by preventing its outputs from being connected together. It also features bus hold capabilities which allow the inputs to be retained if the address lines remain stable. The data set-up and hold times are guaranteed at the BH and BL input thresholds, and the device is characterized for operation from 0°C to 70°C.

The SN74ABTH25245DWG4 features an input designed to accept commonly used TTL input levels (vih=2.2V and vil = 0.8V). It also has an input threshold of 1.2V, so that any input signal level between 0.8V and 2.2V is required for proper device operation. It has a power supply voltage range of 2.0V to 3.6V and includes two separate output enable (G1 and G2) signals that allow multiple transceivers to be connected together with the outputs isolated from each other.

The SN74ABTH25245DWG4 is a 25-pin device with 24 I/O lines, 2 control inputs G1 and G2, and one power supply pin VCC. This transceiver has two independent 8-bit input/output buses (A and B), each of which can be operated in either an output or input mode. The A and B buses can be multiplexed into a single 16-bit channel. Both buses have three-state controls (G1 and G2) that enable data packets to be sent and received on each bus.

The SN74ABTH25245DWG4 has a wide range of applications in the field of digital control. It can be used to create digital control circuits, such as address decoders, memory controllers, and serial to parallel converters. It can also be used in I/O applications, such as bus transceivers and interface level-shifters. It is an ideal choice for communication interface applications, such as Ethernet and USB transceivers.

The SN74ABTH25245DWG4 has two separate output enable (G1 and G2) options that allow the user to isolate the inputs from the outputs. When G1 and G2 are both active (G1 = high and G2 = low) the bus is actively driven with data provided by the inputs. When G1 is inactive (G1 = low) and G2 is active (G2 = high), the bus will be placed in a high impedance state and will not actively drive the outputs. This provides a great deal of flexibility in digital control applications.

The SN74ABTH25245DWG4 also features bus hold capability that is based on the input levels. When enabled, the outputs will remain at the previous logic level (high or low) if the address lines remain unchanged. This provides a great benefit in high speed digital applications, as it prevents the system from losing data due to line noise or other types of interference.

The SN74ABTH25245DWG4 is a versatile, high-speed TTL-compatible 8-bit transceiver. It is ideal for applications requiring high speed data transmission or bus isolation. Its bus hold capabilities and two separate output enable signals make it an ideal choice for digital control and communication interface applications. With its wide operating voltage range and excellent performance, the SN74ABTH25245DWG4 is an excellent choice for the design of any digital control circuit or communication interface.
