MC74F657A Product details

OCTAL BIDIRECTIONAL TRANSCEIVER WITH 8-BIT PARITY GENERATOR CHECKER (3-STATE OUTPUTS)

The MC74F657A and MC74F657B are Octal Bidirectional Transceivers with an 8-bit parity Generator/Checker and 3-state outputs.
The A and B options are faster versions of the F657 and contain eight non-inverting buffers with 3-state outputs and an 8-bit parity generator/checker. These devices are intended for bus-oriented applications. The buffers have a guaranteed current sinking capability of 24 mA at the A ports and 64 mA at the B ports. The Transmit/Receiver (T/R) input determines the direction of the data flow through the bidirectional transceivers. Transmit (active HIGH) enables data from A ports to B ports; Receive (active LOW) enables data from B ports to A ports.

• High-Impedance NPN Base Input for Reduced Loading (20 µA in HIGH and LOW States)
• Ideal in Applications Where High Output Drive and Light Bus Loading are Required (IIL is 20 µA versus Fast std of 600 µA)
• Combines F245 and F280A Functions in One Package
• 3-State Outputs
• B Outputs, PARITY, ERROR, Sink 64 mA and Source 15 mA
• 15 mA Source Current
• Input Diodes for Termination Effects
• Glitchless Outputs During Power Up and Power Down
• High Impedance Outputs During Power Off
• ESD Protection > 4000 Volts

About Motorola, Inc


Motorola, Inc. was an American multinational telecommunications company that was founded in 1928. It was headquartered in Schaumburg, Illinois and was one of the largest providers of mobile phones, telecommunication equipment, and semiconductors. Throughout its history, Motorola was known for its innovation in the field of telecommunications, including the development of the world's first commercially available cellular telephone, the DynaTAC, and the world's first two-way pager, the Pageboy.

In 2011, Motorola split into two separate companies: Motorola Mobility and Motorola Solutions. Motorola Mobility was later acquired by Google in 2012, and is now a subsidiary of Lenovo. Motorola Solutions focuses on public safety and commercial and industrial communication solutions. The company provides a wide range of products including two-way radios, mobile computing devices, and network infrastructure equipment.

Motorola was one of the pioneers of the mobile phone industry and has a rich history of innovation and technological advancements. The company's legacy continues through its subsidiaries and its technology and products continue to be used around the world.
