SN74ALVCH162268DLR 描述

***C: Registered Bus Exchanger 1-Element 56-Pin SSOP

***ark: Universal Bus Function IC; Logic Family:ALVC; Supply Voltage Min:1.65V; Supply Voltage Max:3.6V; Package/Case:56-SSOP; No. of Pins:56; Operating Temperature Range:-40°C to +85°C; Leaded Process Compatible:Yes ;RoHS Compliant: Yes

***as Instruments: This 12-bit to 24-bit registered bus exchanger is designed for 1.65-V to 3.6-V VCC operation. The SN74ALVCH162268 is used for applications in which data must be transferred from a narrow high-speed bus to a wide, lower-frequency bus. The device provides synchronous data exchange between the two ports. Data is stored in the internal registers on the low-to-high transition of the clock (CLK) input when the appropriate clock-enable (CLKEN)\ inputs are low. The select (SEL)\ line is synchronous with CLK and selects 1B or 2B input data for the A outputs. For data transfer in the A-to-B direction, a two-stage pipeline is provided in the A-to-1B path, with a single storage register in the A-to-2B path. Proper control of these inputs allows two sequential 12-bit words to be presented synchronously as a 24-bit word on the B port. Data flow is controlled by the active-low output enables (OEA\, OEB\). These control terminals are registered, so bus direction changes are synchronous with CLK. The B outputs, which are designed to sink up to 12 mA, include equivalent 26- resistors to reduce overshoot and undershoot. To ensure the high-impedance state during power up or power down, a clock pulse should be applied as soon as possible and OE\ should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. Due to OE\ being routed through a register, the active state of the outputs cannot be determined prior to the arrival of the first clock pulse. Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended.
