Product Overview: SN74AC373DBR by Texas Instruments

The SN74AC373DBR is a high-performance, octal transparent D-type latch designed and manufactured by Texas Instruments, a leader in semiconductor solutions. This integrated circuit is part of the 'AC' series, which is known for its advanced high-speed CMOS technology. The device is optimized for operating in systems that require a wide voltage range and high output drive while maintaining low static power consumption.

Key Features

• Logic Type: D-Type Latch
• Number of Channels: 8
• Output Type: Tri-State
• Operating Voltage Range: 2V to 6V
• High-Drive Outputs: ±24-mA Output Drive at 5 V
• Package: SSOP (Shrink Small-Outline Package)
• Temperature Range: -40°C to 85°C
• RoHS: Compliant

The SN74AC373DBR features eight D-type latches with tri-state standard outputs. When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs.

A clear (CLR) input is provided for all latches. When CLR is taken low, all Q outputs are set low, regardless of the other inputs. The tri-state outputs, which feature a 24-mA sink and source capability, are controlled by the output-enable (OE) input. When OE is low, the outputs are in the normal operating mode. However, when OE is high, the outputs are in a high-impedance state, which is particularly useful for interfacing with bus-oriented systems.

Applications

The SN74AC373DBR is suitable for a wide range of applications, including:

• Memory address latching
• Bus-oriented systems
• Data storage and retrieval
• Buffer memory address registers
• System control registers

This device is available in a 20-pin SSOP package, providing a compact footprint for space-constrained applications. The SN74AC373DBR is also characterized for operation from -40°C to 85°C, ensuring reliable performance across a broad range of environmental conditions.

With its combination of high-speed performance, wide operating voltage range, and robust output drive, the SN74AC373DBR from Texas Instruments is an excellent choice for designers looking for a reliable and versatile octal latch solution.
