SN74HCT373PWRE4 Octal Transparent D-Type Latch from Texas Instruments

The SN74HCT373PWRE4 is a high-performance, octal transparent D-type latch designed and manufactured by Texas Instruments. This integrated circuit is part of the 'HCT' family of logic devices that are characterized by their high-speed CMOS technology. The device is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working memory in a wide range of digital applications.

The SN74HCT373PWRE4 features eight D-type latches with 3-state true outputs. The transparent nature of the latches means that while the latch-enable (LE) input is high, the Q outputs will follow the data (D) inputs. When LE is taken low, the Q outputs will be latched at the level of the D inputs that were set up at the time the LE was last high. The 3-state outputs, which can be put in a high-impedance state, allow for bus-oriented applications.

The device is designed to interface directly with the high-speed CMOS logic operating at 5V power supply. It also possesses the ability to drive 15 LSTTL loads, which allows for a considerable amount of flexibility in mixed-technology systems. The SN74HCT373PWRE4 has a wide operating voltage range of 4.5V to 5.5V, which ensures stable operation in a variety of conditions.

For design and assembly convenience, this product comes in a TSSOP (Thin Shrink Small Outline Package) with 20 pins, under the part number SN74HCT373PWRE4. It is also characterized for operation from -40°C to 85°C, making it suitable for industrial applications requiring a wide temperature range.

Key features of the SN74HCT373PWRE4 include:

• 8-bit transparent D-type latches with 3-state outputs
• Wide operating voltage range of 4.5V to 5.5V
• Direct LSTTL input logic compatibility, V_CC = 5V ±0.5V
• High drive capability: 15 LSTTL loads
• Low power consumption
• Temperature range from -40°C to 85°C
• TSSOP-20 packaging for efficient PCB space utilization

Overall, the SN74HCT373PWRE4 is an excellent choice for designers looking for a reliable and versatile octal latch that can be used in a multitude of digital systems. Its compatibility with various logic families and its robust design make it a solid choice for ensuring data integrity in your digital applications.
