3.3-V ABT 16-BIT BUS TRANSCEIVERS WITH 3-STATE OUTPUTS

The LVTH16646 devices SN54LVTH16646 SN74LVTH16646 are 16-bit Bus Transceivers designed for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL Interface to a 5-V system environment. These devices CAN be used as two 8-bit transceivers or one 16-bit transceiver. Data on the A or B bus is clocked into the Registers on the low-to-high transition of the appropriate Clock (CLKAB or CLKBA) input. Figure 1 illustrates the four fundamental bus-management functions that CAN be performed with the LVTH16646 devices By Texas Instruments
