3.3-V ABT OCTAL BUS TRANSCEIVERS AND REGISTERS WITH 3-STATE OUTPUTS

These octal Bus Transceivers SN54LVTH2952 SN74LVTH2952 and Registers are designed specifically for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL Interface to a 5-V system environment. The LVTH2952 devices consist of two 8-bit back-to-back Registers that store data flowing in both directions between two bidirectional buses. Data on the A or B bus is stored in the Registers on the low-to-high transition of the Clock (CLKAB or CLKBA) input, provided that the clock-enable (CLKENAB or CLKENBA) input is low. Taking the output-enable (OEAB or OEBA) input low accesses the data on either port. Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid Logic level. When VCC is between 0 and 1.5 V, the devices are in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.5 V, 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.
