74HC164 The HTC74HC164 is an 8-bit edge-triggered shift registers with serial input and parallel output. A LOW-to-HIGH transition on the CP will shifts the data one place to the right which is the logical AND of DSA and DSB.
-
74HC165 The HTC74HC165 is an 8-bit parallel-load shift register that, when clocked, shifts the data toward a serial (QH) output. Parallel-in access to each stage is provided by eight individual direct data (A-H) inputs that are enabled by a low level at shift/load (SH/¯LD) input.
-
74HC245 The HTC74HC245 is designed for asynchronous communication between data buses. When the direction-control(DIR) is high, data is transmitted from the A bus to the B bus.
-
74HC595 The HTC74HC595 contains an 8-bit register with asynchronous reset input and an 8-bit latch with output.
-
74HC125 The HTC74HC125 is a quad buffer/line driver with 3-state outputs controlled by the output enable inputs (n¯OE).
-
74HC244 The HTC74HC244 is an 8-bit buffer/line driver with 3-state outputs. The device can be used as two 4-bit buffers or one 8-bit buffer.
-
74HC273 The HTC74HC273 devices are positive-edge-triggered D-type flip-flops with a direct active low clear (CLR) input.
-
74HC373 The HTC74HC373 consists of eight D-type transparent latches with 3-state outputs.
-
74HC374 The HTC74HC374 is an octal edge-triggered D-type flip-flop with 3-state outputs and 8 channels.
