Latch
High-Voltage Types (20-Volt Rating)
The RCA-CD40428 types contain four latch
circuits, each strobed by a common clock.
Complementary buffered outputs are availa-
ble from each circuit. The impedance of the
n- and p-channel output devices is balanced
and all outputs are electrically identical.
I nformation present at the data input is
transferred to outputs Q and
Q
during the
CLOCK level which is programmed by the
POLARITY input. For POLARITY
=
0 the
transfer occurs during the 0 CLOCK level
and for POLARITY
=
1
the transfer occurs
during the
1
CLOCK level. The outputs
follow the data input providing the CLOCK
and POLARITY levels defined above are
present. When a CLOCK transition occurs
(positive for POLARITY
=
0 and negative
for PO LAR ITY
=
1)
the information present
at the input during the CLOCK transition is
retained at the outputs until an opposite
CLOCK transition occurs.
\
The CD40428 types are supplied in 16-lead
hermetic dual-in-line ceramic packages (D
and F suffixes). 16-lead dual-in-line plastic
package
(E
suffiX), 16-lead ceramic flat
package
(K
suffix), and
In
chip form
(H
suffix).
