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. 1 56 2 55 3 54 4 53 5 52 6 51 7 50 8 49 9 48 10 47 11 46 12 45 13 44 14 43 15 42 16 41 17 40 18 39 19 38 20 37 21 36 22 35 23 34 24 33 25 32 26 31 27 30 28 29 OEB1 OEB2 SEL0 GND 1B1 1B2 VCC 1B3 1B4 2B1 GND 2B2 2B3 2B4 3B1 3B2 3B3 GND 3B4 4B1 4B2 VCC 4B3 4B4 GND SEL1 OEB3 OEB4 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.

POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 1 SN54ABTH16460, SN74ABTH16460 4-TO-1 MULTIPLEXED/DEMULTIPLEXED TRANSCEIVERS WITH 3-STATE OUTPUTS SCBS207F – OCTOBER 1992 – REVISED MAY 1997 description (continued) 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 –55°C to 125°C. The SN74ABTH16460 is characterized for operation from –40°C to 85°C.
