DM74LS377
Octal D-Type Flip-Flop with Common Enable and Clock
General Description
The DM74LS377 is an 8-bit register built using advanced
low power Schottky technology. This register consists of
eight D-type flip-flops with a buffered common clock and a
buffered common input enable. The device is packaged in
the space-saving (0.3 inch row spacing) 20-pin package.
Features
s 8-bit high speed parallel registers
s Positive edge-triggered D-type flip-flops
s Fully buffered common clock and enable inputs
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
