Descripción general

Description

SN74HCS574QPWRQ1 is an 8-bit, edge-triggered D-type register with 3-state outputs from TI’s 74HCS CMOS family. It has eight data inputs (D0–D7), a single clock (CP), and eight tri-state outputs (Q0–Q7) controlled by an active-low output enable (OE). On the rising edge of CP, the D inputs are latched to Q outputs; OE can tri-state all outputs to allow bus sharing when disabled. The device operates from 2.0 to 6.0 V (typical 5 V) with CMOS inputs that are TTL-compatible. It’s commonly used for data storage, bus buffering, and interfacing microprocessors or other digital ICs. The QPWRQ1 suffix indicates TI’s RoHS-compliant packaging variant for this device.

Features

Here are concise features of SN74HCS574QPWRQ1:
- 8-bit, edge-triggered D-type register (D0–D7) with Q0–Q7 outputs
- Rising-edge clock (CLK) captures data
- 3-state outputs with Output Enable (OE\) input; outputs go High-Z when OE\ is high
- TTL-compatible inputs; High-speed CMOS (HCS) device
- Vcc typically 4.5V–5.5V (5V nominal)
- Low static/dynamic power consumption
- Suitable for bus interfacing and data buffering
- 20-pin plastic package, RoHS-compliant (QPWRQ1)
- Nondestructive reads; data retained until next clock edge
Applications: microprocessor/data buses, latch/register buffering, and parallel data conversion interfaces.

Package

20-pin Plastic Small-Outline (SOIC) package, RoHS-compliant (Q1 tape-and-reel available).

Pinout

- Pin count: 20 pins (DIP20/SOIC-20/TSSOP-20 variants in the SN74HCS574QPWRQ1 family).
- Function: 8-bit D-type edge-triggered register with 3-state outputs. It samples D0–D7 on the rising edge of CLK and presents the data on Q0–Q7; outputs are enabled/disabled by the active-low Output Enable (OE) input (high → tri-state; low → valid outputs).

Manufacturer

- Manufacturer: Texas Instruments (TI)
- What kind of company: A multinational American semiconductor design and manufacturing company that specializes in analog, mixed-signal, and embedded processing ICs and related semiconductor products for a wide range of industries.

Application

Application areas: Bus interface and buffering for microprocessors/microcontrollers; address latch for multiplexed buses (e.g., 8086); data storage and buffering for peripherals; tri-state bus driver/isolator in memory-mapped I/O; pipeline/register-file style data-path buffering.

Equivalent

Equivalent parts (octal D-type register with 3-state outputs) include TI variants: SN74HC574, SN74HCT574, SN74HCP574, SN74HCS574, SN74LVC574. Other vendors offer 74HC574, 74HCT574, 74LVC574. Note pinout, supply voltage, and I/O thresholds may differ; verify datasheets and cross-reference before substitution.
