ADG428

LC2MOS可锁存4- / 8通道高性能模拟多路复用器 LC2MOS Latchable 4-/8-Channel High Performance Analog Multiplexers

Product Details

The is a monolithic CMOS analog multiplexer comprising eight single channels. On-chip address and control latches facilitate microprocessor interfacing. The ADG428 switches one of eight inputs to a common output as determined by the 3-bit binary address lines A0, A1 and A2. An EN input on both devices is used to enable or disable the device. When disabled, all channels are switched OFF. All the control inputs, address and enable inputs are TTL compatible over the fully specified operating temperature range. This makes the part suitable for bus-controlled systems such as data acquisition systems, process controls, avionics and ATEs because the TTL compatible address latches simplify the digital interface design and reduce the board space required.

Product Highlights

1. Extended Signal Range

The ADG428/ADG429 are fabricated on an enhanced LC2MOS process, giving an increased signal range that extends to the supply rails.

2. Low Power Dissipation

3. Low RON

4. Single/Dual Supply Operation

5. Single Supply Operation

For applications where the analog signal is unipolar, the ADG428/ADG429 can be operated from a single rail power supply. The parts are fully specified with a single +12 V power supply and will remain functional with single supplies as low as +5 V.
