Product Overview: CD74HCT573M96 from Texas Instruments
The CD74HCT573M96 is a high-speed CMOS Logic Octal Transparent Latch with 3-state outputs designed and manufactured by Texas Instruments. This integrated circuit is a part of TI's high-speed HCT family and is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working memory. With its octal transparent latch feature, it allows data to flow from the input to the output when the latch enable (LE) input is high, and latches the data when LE is low.
The device comes in a 20-pin SOIC package, offering a compact footprint for space-conscious applications. The CD74HCT573M96 operates at a voltage range of 4.5V to 5.5V, making it compatible with TTL levels, and it also features a low power consumption which is typical for CMOS devices. This makes it an excellent choice for interfacing with microprocessors or microcontrollers within 5V systems.
The 3-state outputs of the CD74HCT573M96 are controlled by the output enable (OE) input. When OE is low, the device's outputs are active and reflect the data set at the inputs. When OE is high, the outputs are in a high impedance state, which effectively disconnects them from the bus. This feature allows for multiple devices to be connected to the same output bus without interference, providing an efficient and flexible bus management system.
The CD74HCT573M96 boasts a high fan-out capability and provides a balanced propagation delay and transition times. This ensures reliable and fast operation, which is essential for high-speed digital systems. The device also includes input protection that shields it from static discharge and transient excess voltage, increasing its robustness and longevity in demanding environments.
In summary, Texas Instruments' CD74HCT573M96 is a versatile and reliable component for digital systems requiring high-speed octal latches with 3-state outputs. With its compatibility with TTL levels, low power consumption, and robust protection features, it stands as a smart choice for designers looking to create efficient and reliable digital logic systems.
