description
These 18-bit universal bus transceivers consist of
storage elements that can operate either as
D-type latches or D-type flip-flops to allow data
flow in transparent or clocked modes.
Data flow in each direction is controlled by
output-enable (OEAB and OEBA), latch-enable
(LEAB and LEBA), and clock (CLKAB and
CLKBA) 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 bus data
is stored in the latch/flip-flop on the low-to-high transition of CLKAB. When OEAB is high, the outputs are active.
When OEAB is low, 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, and CLKBA. The output enables are
complementary (OEAB is active high and OEBA is active low).
To ensure the high-impedance state during power up or power down, OE should be tied to GND through a
pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the
driver.
The SN74ABT16501A is available in TI’s shrink small-outline package (DL), which provides twice the I/O pin
count and functionality of standard small-outline packages in the same printed-circuit-board area.
The SN54ABT16501A is characterized over the full military temperature range of –55
°
C to 125
°
C. The
SN74ABT16501A is characterized for operation from –40
°
C to 85
°
C.
