Description : 8-Bit ADCs with Serial Interface and Configurable Input Multiplexer

Description
WM0834 and WM0838 are 8-Bit analogue to digital Converters (ADC) with configurable 4-input and 8-input Multiplexers respectively and a Serial I/O interface.
Assignment of the Multiplexer inputs is configured before each conversion via the Serial data input to give single-ended or differential operation for the selected inputs. A mixture of input configurations can be used in the same application. WM0838 also has a pseudo-differential configuration where all 8 inputs can be refered to a common input at an arbitrary voltage.

Features
• Functionally Equivalent to National Semiconductor ADC0834 and ADC0838 without the Internal Zener Regulator Network
• 4-input (WM0834) or 8-input (WM0838) MUX Options

Description : 8-Channel Analog Multiplexer with Serial Interface

DESCRIPTION
The LTC®1390 is a high performance CMOS 8-to-1 analog Multiplexer. It features a 3-wire digital interface with a bidirectional data retransmission feature, allowing it to be wired in series with a Serial A/D converter while using only one Serial port. The interface also allows several LTC1390s to be wired in series or parallel, increasing the number of MUX channels available using only a single digital port. All the above features are also valid when LTC1390 operates as a deMultiplexer such as with a D/A converter.

FEATURES
■ 3-Wire Serial Digital Interface
■ Data Retransmission Allows Series Connection with Serial A/D Converters
■ Single 3V to ±5V Supply Operation
■ Analog Inputs May Extend to Supply Rails
■ Low Charge Injection
■ Low RON: 75Ω Max
■ Low Leakage: ±5nA Max
■ Guaranteed Break-Before-Make
■ TTL/CMOS Compatible for All Digital Inputs
■ Cascadable to Allow Additional Channels
■ Can Be Used as a DeMultiplexer

APPLICATIONS
■ Data Acquisition Systems
■ Communication Systems
■ Signal Multiplexing/Demultiplexing

Description : 16-bit Serial/parallel-in, Serial-out shift register (3-State)

DESCRIPTION
The 74F676 contains 16 flip-flops with provision for synchronous parallel or Serial entry and Serial output. When the mode (M) input is High, information present on the parallel data (D0–D15) inputs is entered on the falling edge of the clock pulse (CP) input signal. When M is Low, data is shifted out of the most significant bit position while information present on the Serial (SI) input shifts into the least significant bit position. A High signal on the chip select (CS) input prevents both parallel and Serial operations.

FEATURES
• 16-bit parallel-to-Serial conversion
• 16-bit Serial-in, Serial-out
• Chip select control
• Power supply current 48mA typical
• Shift frequency 110MHz tyical
• Available in 300mil-wide 24-pin Slim DIP package
