The HD74HC298P is a Quad 2-Input Multiplexer with Storage, manufactured by Hitachi. It features high-speed CMOS logic and is designed for data selection and storage applications. The device incorporates four 2-input multiplexers, each with its own storage latch, providing a versatile solution for data routing and temporary data holding.

Applications:

• Data selection
• Data routing
• Data storage
• Address selection in memory systems
• Peripheral selection in microcomputer systems

Features:

• High Speed Operation: tpd = 15 ns (typ.) at VCC = 5V
• Low Power Dissipation: ICC = 4 μA (max.) at Ta = 25°C
• High Noise Immunity: VNIH = VNIL = 28 % VCC (min.)
• Output Drive Capability: 10 LSTTL Loads
• Wide Operating Voltage Range: VCC = 2 V to 6 V
• Buffered Inputs and Outputs

Benefits:

• Enables fast and efficient data selection and routing.
• Reduces power consumption, making it suitable for battery-operated devices.
• Provides reliable operation in noisy environments.
• Offers flexibility in system design with its wide operating voltage range.
• Simplified interfacing with other logic devices due to buffered inputs and outputs.

Additional Details:

The HD74HC298P is available in a 16-pin DIP package. It operates over a temperature range of -40°C to +85°C. Each multiplexer has two data inputs, a select input, a latch enable input, and a data output. When the latch enable input is low, the output follows the selected data input. When the latch enable input is high, the output is latched, storing the last selected data value.
