Product specification
74ALS573B/74ALS574A
74ALS573B Octal transparent latch (3-State)
74ALS574A Octal D flip-flop (3-State)
FEATURES
74ALS573B is broadside pinout version of 74ALS373
74ALS574A is broadside pinout version of 74ALS374
Inputs and outputs on opposite side of package allow easy
interface to microprocessors
Useful as an input or output port for microprocessors
3-State outputs for bus interfacing
Common output enable
74ALS563A and 74ALS564A are inverting version of 74ALS573B
and 74ALS574A respectively
DESCRIPTION
The 74ALS573B is an octal transparent latch coupled to eight
3-State output devices. The two sections of the device are controlled
independently by enable (E) and output enable (OE) control gates.
The 74ALS573B is functionally identical to the 74ALS373 but has a
broadside pinout configuration to facilitate PC board layout and
allow easy interface with microprocessors.
The data on the D inputs is transferred to the latch outputs when the
enable (E) input is High. The latch remains transparent to the data
input while E is High, and stores the data that is present one setup
time before the High-to-Low enable transition.
The 74ALS574A is functionally identical to the 74ALS374 but has a
broadside pinout configuration to facilitate PC board layout and
allow easy interface with microprocessors.
It is an 8-bit edge triggered register coupled to eight 3-State output
buffers. The two sections of the device are controlled independently
by clock (CP) and output enable (OE) control gates.
The register is fully edge triggered. The state of the D input, one
setup time before the Low-to-High clock transition is transferred to
the corresponding flip-flop’s Q output.
The active-Low output enable (OE) controls all eight 3-State buffers
independent of the latch operation. When OE is Low, latched or
transparent data appears at the output.
When OE is High, the outputs are in high impedance “off” state,
which means they will neither drive nor load the bus.
