Product Overview: 74HCT640DB,118

The 74HCT640DB,118 is a high-speed Si-gate CMOS device designed and manufactured by NXP Semiconductors, a leader in the electronics industry. This integrated circuit is part of the 74HCT family, which is known for its compatibility with TTL (Transistor-Transistor Logic) while offering the low power consumption of CMOS technology. The 74HCT640DB,118 is an octal transceiver featuring non-inverting 3-state outputs.

Key Features

• Logic Type: Octal Transceiver
• Logic Family: HCT
• Number of Pins: 20
• Package Type: SSOP (Shrink Small Outline Package)
• Supply Voltage Range: 4.5V to 5.5V
• Operating Temperature Range: -40°C to +125°C

The 74HCT640DB,118 is designed for asynchronous communication between data buses. The control function implementation minimizes external timing requirements. This device can be used as two 4-bit transceivers or one 8-bit transceiver. It allows data to flow from the A inputs to the Y outputs, or from the Y inputs to the A outputs, depending on the logic level at the direction control (DIR) input. The output enable (OE) input can be used to disable the device so that the buses are effectively isolated.
