74HC157 datasheet

Description

The 74HC157 high speed Quad 2-to-1 Line data selector/Multiplexers utilizes advanced silicon-gate CMOS tech nology. It possesses the high noise immunity and low power consumption of standard CMOS integrated circuits, as well as the ability to drive 10 LS-TTL loads.

This device consists of four 2-input digital multiplexers with common select and STROBE inputs. When the STROBE input is at logical “0” the four outputs assume the values as selected from the inputs. When the STROBE input is at a logical “1” the outputs assume logical “0”.

Part Number: AD8170

Function: 250 MHz, 10 ns Switching Multiplexers w / Amplifier

Package: DIP, SOP 8 Pin Type

Manufacturer: Analog Devices

Pinouts:

AD8170 datasheet

 

Description

The AD8170(2:1) and AD8174(4:1) are very high speed buffered multiplexers. These multiplexers offer an internal current feedback output amplifier whose gain can be programmed via external resistors and is capable of delivering 50mA of output current. They offer –3 dB signal bandwidth of 250 MHz and slew rate of greater than 1000 V/µs. Additionally, the AD8170 and AD8174 have excellent video specifications with low differential gain and differential phase error of 0.02% and 0.05°and 0.1 dB flatness out to 80 MHz. With a low 78dB of crosstalk and better than 88 dB isolation, these devices are useful in many high speed applications. These are low power devices consuming only 9.7 mA from a ±5 V supply.

Features

1. Fully Buffered Inputs and Outputs

2. Fast Channel Switching: 10 ns

3. Internal Current Feedback Output Amplifier

4. High Output Drive: 50 mA

5. Flexible Gain Setting via External Resistor(s)

6. Fast Settling Time of 15 ns to 0.1%

7. Low Power: < 10 mA

8. Excellent Video Specifications (RL= 150 V, G = +2)

9. Low Crosstalk of –78 dB @ 5 MHz

10. High Disable Isolation of –88 dB @ 5 MHz

11. High Shutdown Isolation of –92 dB @ 5 MHz

12. Fast Output Disable Feature for Connecting Multiple

Applications:

1.Pixel Switching for “Picture-In-Picture”

2. LCD and Plasma Displays

3. Video Routers
