Part Number: SN74ALVTH16827VR
Function: 2.5-V/3.3-V 20-BIT BUFFERS/DRIVERS WITH 3-STATE OUTPUTS
Package: TVSOP 56 Pin Type
Manufacturer: Texas Instruments
The SN74ALVTH16827VR, 74ALVTH16827 devices are 20-bit buffers/line drivers designed for 2.5-V or 3.3-V VCCoperation, but with the capability to provide a TTL interface to a 5-V system environment.
The devices are composed of two 10-bit sections with separate output-enable signals. For either 10-bit buffer section, the two output-enable (1OE1and 1OE2, or 2OE1and 2OE2) inputs must be low for the corresponding Y outputs to be active. If either output-enable input is high, the outputs of that 10-bit buffer section are in the high-impedance state.
When VCC is between 0 and 1.2 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.2 V, OEshould be tied to VCCthrough a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
1. State-of-the-Art Advanced BiCMOS Technology (ABT) WidebusE Design for 2.5-V and 3.3-V Operation and Low Static Power Dissipation
2. Support Mixed-Mode Signal Operation (5-V Input and Output Voltages With 2.3-V to 3.6-V VCC)
