description
This 17-bit registered bus transceiver combines
D-type latches and D-type flip-flops to allow data
flow in transparent, latched, and clocked modes.
It provides for a copy of CLKAB at GTL logic levels
(CLKOUT). It also provides a conversion of the
GTL clock to a TTL environment (CLKIN).
The B port operates at GTL levels while the A port
and control pins are compatible with LVCMOS,
LVTTL, or 5-V TTL logic levels.
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 or latch-enable can be controlled by the chip-enable (CEAB
and CEBA) 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 CEAB is low and CLKAB is held at a high or low logic level. If LEAB is low,
the A-bus data is stored in the latch/flip-flop on the low-to-high transition of CLKAB if CEAB is also low.
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 CEBA.
To ensure the high-impedance state during power-up or power-down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN74GTL16615 is characterized for operation from 0
°
C to 70
