description (continued)
Data flow in each direction is controlled by output-enable (OEAB and OEBA), latch-enable (LEAB and LEBA),
and clock (CLKAB and CLKBA) inputs. The clock can be controlled by the clock-enable (CLKENAB and
CLKENBA) inputs. For A-to-B data flow, the device operates in the transparent mode when LEAB is high. When
LEAB is low, the A data is latched if CLKAB is held at a high or low logic level. If LEAB is low, the A data is stored
in the latch/flip-flop on the low-to-high transition of CLKAB. Output enable OEAB is active low. When OEAB is
low, the outputs are active. When OEAB is high, the outputs are in the high-impedance state.
Data flow for B to A is similar to that of A to B, but uses OEBA, LEBA, CLKBA, and CLKENBA.
This device is fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry
disables the outputs, preventing damaging current backflow through the device when it is powered down. The
power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,
which prevents driver conflict.
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, 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.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN54ALVTH16601 is characterized for operation over the full military temperature range of –55
°C to
125
°C. The SN74ALVTH16601 is characterized for operation from –40°C to 85°C.
