Description

The TC74HC374P is an Octal D-Type Flip-Flop with 3-State Outputs manufactured by Toshiba Semiconductor and Storage. This device features eight D-type flip-flops with a common clock (CLK) and output enable (OE) input. Data at the D inputs is transferred to the Q outputs on the positive-going edge of the clock pulse. The 3-state outputs allow for connection to a common bus, enabling multiple devices to share the bus without contention.

Applications

  • Buffer Registers
  • Address Latches
  • Data Storage
  • Memory Interfacing
  • Microprocessor Systems

Features

  • High Speed: tpd = 14 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
  • Symmetrical Output Impedance: |IOH| = IOL = 4 mA (min)
  • Wide Operating Voltage Range: VCC = 2V to 6V
  • 3-State Outputs for Bus Interfacing

Benefits

  • Improved System Performance: High-speed operation allows for faster data storage and retrieval.
  • Reduced Power Consumption: Low power dissipation minimizes energy usage and heat generation.
  • Enhanced Noise Immunity: High noise immunity ensures reliable operation in noisy environments.
  • Versatile Interfacing: The 3-state outputs simplify bus interfacing and prevent bus contention.
  • Simplified System Design: Symmetrical output impedance reduces signal reflections and improves signal integrity.
  • Flexible Operating Voltage: The wide operating voltage range provides design flexibility and compatibility with different power supply levels.
  • Efficient Data Storage: Eight flip-flops in a single package provide efficient data storage and buffering.

Additional Details

The TC74HC374P's operation is controlled by the clock (CLK) and output enable (OE) inputs. Data present at the D inputs is latched into the flip-flops on the positive-going edge of the clock pulse. When the output enable (OE) is low, the Q outputs are enabled, allowing data to be read from the flip-flops. When OE is high, the outputs are disabled and placed in a high-impedance state, effectively disconnecting the device from the bus.

This device is available in a plastic Dual In-Line Package (DIP). The operating temperature range is generally from -40°C to +85°C. Proper decoupling capacitors should be used near the power supply pins for optimal performance. Refer to the official Toshiba datasheet for detailed specifications and application guidelines.
