74AC245 datasheet



The 74AC245 octal bus transceivers are designed for asynchronous two-way communication
between data buses. The control-function implementation minimizes external timing
requirements. When the output-enable (OE) is low, the device passes noninverted data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction control (DIR) input.

A high on (OE) disables the device so that the buses are effectively isolated.
To ensure the high-impedance state during power up or power down, OEshould be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

LAN8710A Datasheet PDF – 10/100 Ethernet Transceiver

Part Number : LAN8710A

Function : Small Footprint MII/RMII 10/100 Ethernet Transceiver with HP Auto-MDIX and flexPWR

Pakcage : 32-pin QFN Type

Manufacturers : SMSC -> Microchip


LAN8710A Transceiver

Description :

The LAN8710A / LAN8710Ai is a low-power 10BASE-T/100BASE-TX physical layer (PHY) transceiver
with variable I/O voltage that is compliant with the IEEE 802.3-2005 standards. The LAN8710 / LAN8710Ai supports communication with an Ethernet MAC via a standard MII (IEEE
802.3u)/RMII interface. It contains a full-duplex 10-BASE-T/100BASE-TX transceiver and supports
10Mbps (10BASE-T) and 100Mbps (100BASE-TX) operation. The LAN8710A/LAN8710Ai implements
auto-negotiation to automatically determine the best possible speed and duplex mode of operation. HP Auto-MDIX support allows the use of direct connect or cross-over LAN cables.
