AD8184ANZ

Overview

The AD8184ANZ is a high-speed 4-to-1 video multiplexer manufactured by Analog Devices Inc. It features a -3 dB signal bandwidth of 700 MHz and a slew rate exceeding 750 V/µs. The device operates on ±5 V supplies with a quiescent current of 4.4 mA when enabled. Key performance metrics include a channel switching time of 10 ns, settling time to 0.1% in 15 ns, and all-hostile crosstalk of -95 dB at 5 MHz. It offers high 'OFF' isolation of -115 dB and differential gain/phase errors of 0.01% and 0.01° respectively. The component is housed in a 14-lead plastic DIP package.

Feature Summary

• Fully buffered inputs and outputs ensure unidirectional signal paths with minimal loading effects.
• Fast channel switching capability supports pixel switching and picture-in-picture applications.
• High-speed disable feature allows multiple devices to be connected in parallel without bus loading.
• Low glitch magnitude and excellent video specifications make it suitable for professional video routing.

Applications

• Video switchers and routers
• Pixel switching for LCD and plasma displays
• Color document scanners

Procurement Notes

Verify the ordering suffix ANZ corresponds to the 14-lead Plastic DIP (N-14) package variant. Confirm the temperature range is specified as -40°C to +85°C. Ensure the part number matches the REV. 0 datasheet specifications for accurate parameter alignment during procurement.

Selection Notes

Select this component for applications requiring high bandwidth and fast settling times. Consider the 14-lead DIP package for through-hole mounting requirements. Evaluate power supply constraints as the device requires dual ±5 V rails. Check input/output impedance matching needs against the 28 Ω output resistance specification.

Part Context

The AD8184 belongs to a family of high-speed video multiplexers that includes single and dual 2-to-1 variants such as the AD8180 and AD8182. These devices utilize a complementary bipolar process to achieve wide bandwidth and low power consumption. The AD8184 specifically provides four input channels controlled by two-bit binary logic.

Replacement Considerations

The AD8184 is pin compatible with HA4314 and GX4314 video switchers. Verify electrical specifications match before substituting these legacy parts. No other direct substitute part numbers are confirmed in the provided documentation.
