4-to-1 Multiplexer/Demultiplexer Transceivers With 3-State Outputs

The 'ABTH16460 are 4-bit to 1-bit multiplexed registered transceivers used in applications where four separate data paths must be multiplexed onto or demultiplexed from a single data path. Typical applications include multiplexing and/or demultiplexing of address and data information in Microprocessor or bus-interface applications. These devices also are useful in memory-interleaving applications.
Five 4-bit I/O ports (1A-4A, 1B1-4, 2B1-4, 3B1-4, and 4B1-4) are available for address and/or data transfer. The output-enable (OEB, OEB1-OEB4, and OEA) inputs control the bus-transceiver functions. These control signals also allow 4-bit or 16-bit control, depending on the OEB level.
Address and/or data information CAN be stored using the internal storage Latches Flip-Flops The latch-enable (LEB1-LEB4, LEBA, and LEAB1-LEAB4) and Clock clock-enable (CLK/CLKEN) inputs are used to control data storage. When either one of the latch-enable inputs is high, the latch is transparent (clock is a don't care as long as the latch enable is high). When the latch-enable input goes low (providing that the Clock does not transit from low to high), the data present at the inputs is latched and remains latched until the latch-enable input is returned high. When the Clock enable is low and the corresponding latch enable is low, data CAN be clocked on the low-to-high transition of the Clock When either the Clock enable or the corresponding latch enable is high, the Clock is a don't care.
Four select pins (SEL0, SEL1, CE_SEL0, and CE_SEL1) are provided to multiplex data (A port), or to select one of four Clock enables (B port). This allows the user the flexibility of controlling one bit at a time.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid Logic level.
When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 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.
The SN54ABTH16460 is characterized for operation over the full military temperature range of -55C to 125C. The SN74ABTH16460 is characterized for operation from -40C to 85C.
