HD74ALVCH16501
18-bit Universal Bus Transceivers with 3-state Outputs
ADE-205-168A (Z)
2nd. Edition
December 1999
Description
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). Active
bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
