Quad 1-of-2 Line Data Selector/Multiplexer

General Description These data selectors/multiplexers contain inverters and drivers to supply full on-chip data selection to the four output gates. A separate strobe input is provided. A 4-bit word is selected from one of two sources and is routed to the four outputs. The ALS157 presents true dat

Synchronous Four-Bit Counter

General Description These synchronous presettable counters feature an internal carry look ahead for application in high speed counting designs. The DM74ALS162B is a four-bit decade counter, while the DM74ALS161B and DM74ALS163B are four-bit binary counters. The DM74ALS161B clears asynchronously,

8-Bit Parallel In/Serial Out Shift Register

General Description The DM74ALS165 is an 8-bit serial register that, when clocked, shifts the data toward serial output, QH. Parallel-in access to each stage is provided by eight individual direct data inputs that are enabled by a low level at the SH/LD input. The DM74ALS165 also features a clock
