DESCRIPTION

The HCC4042B (extended temperature range) and

HCF4042B (intermediate temperature range) are

monolithic integrated circuit, available in 16-lead

dual in-line plastic or ceramic package and plastic

micro package.

The HCC/HCF4042B types contain four latch cir-

cuits, each strobed by a common clock. Com-

plementary buffered outputs are available from

each circuit. The impedance of the n- and p-channel

output devices is balanced and all outputs are elec-

trically identical.

Information present at the data input is transferred

to outputs Q and Q during the CLOCK level which

is programmed by the POLARITY input. For PO-

LARITY = 0 the transfer occurs during the 0 CLOCK

level and for POLARITY = 1 the transfer occurs dur-

ing the 1 CLOCK level. The outputs follow the data

input providing the CLOCK and POLARITY levels

defined above are present. When a CLOCK transi-

tion occurs (positive for POLARITY = 0 and negative

for POLARITY = 1) the information present at the

input during the CLOCK transition is retained at the

outputs until an opposite CLOCK transition occurs.
