Description

The 74F640 is an octal bus transceiver with inverting 3-state outputs, designed for asynchronous two-way communication between data buses. The IC can function as both a driver and receiver, and its inverting outputs allow for flexible signal control in bus-oriented systems. It is commonly used in memory interfacing and microprocessor-based systems for bidirectional data flow control.

Features

  • Octal bus transceiver with 3-state inverting outputs
  • Asynchronous bidirectional data transmission
  • Separate control inputs for direction (DIR) and output enable (OE)
  • High-speed operation with typical propagation delay of 4 ns
  • TTL-compatible inputs and outputs
  • Inverting output logic for data inversion
  • Standard DIP-20 package for easy through-hole mounting

Specifications

  • Logic Family: 74F (Fast TTL)
  • Number of Transceivers: 8 (octal)
  • Output Type: Inverting, 3-state
  • Supply Voltage (Vcc): 4.5V to 5.5V
  • Input Low Voltage (VIL): Max 0.8V
  • Input High Voltage (VIH): Min 2.0V
  • Output Low Voltage (VOL): Max 0.5V (at IOL = 20mA)
  • Output High Voltage (VOH): Min 2.4V (at IOH = -3mA)
  • Power Dissipation: 65 mW (typical)
  • Propagation Delay: 4 ns (typical)
  • Operating Temperature Range: 0°C to 70°C
  • Package Type: DIP-20
