ZR78L052C This device is intendedfor switching between video and chroma signals such as CVBS, SVHS, baseband CVBS, MAC. Each input clamp mode, each output gain, all switching are controlled throughthe I2C bus.The 8 outputscan be setseparately in high impedance state, to enable parallel DC connection of several devices (up to 4)....
ZR78L052C The 74LVQ08 is a low voltage CMOS QUAD 2-INPUT AND GATE fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and low noise 3.3V applications.
The internal circuit is composed of 2 stages including buffer output, which enables high noise immunity and stable output.
All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. ...
ZR78L052C The SN74BCT979 is a 9-bit to 9-bit parity transceiver with transparent latches. The device can operate as a feed-through transceiver, or it can generate/check parity from the 8-bit data bus in either direction. It has a guaranteed current-sinking capability of 24 mA at the A bus and 100 mA at the open-collector B bus.
The SN74BCT979 features independent latch-enable (LEAB, LEBA) inputs for the A-to-B direction and the B-to-A direction, an ODD/EVEN input to select odd or even parity, and separate error-signal (ERRA, ERRB) outputs for checking parity.
When communication between buses occurs, parity is generated and passed on to either bus as APARO or BPAR. Error detection of the parity generated from AI1–AI8 and B1–B8 can be checked by ERRA and ERRB, providing LEAB and LEBA are high and the mode select (SEL) is low. If SEL is high, the communication between buses is in a feed-through mode where parity is still generated and checked as ERRA and ERRB.
The SN74BCT979 features open-collector driver outputs (B port) with a series Schottky diode to reduce capacitive loading to the bus. By using a 2-V pullup on the bus, the output signal swing will be approximately 1 V, which reduces the power necessary to drive the bus load capacitance. The driver outputs are capable of driving an equivalent dc load of as low as 10 Ω.
The transceiver has a precision threshold set by an internal bandgap reference to give accurate input thresholds over VCC and temperature variations.
This transceiver is compatible with backplane transceiver logic (BTL) technology at significantly reduced power dissipation per channel.
The SN74BCT979 is characterized for operation from 0°C to 70°C. ...
