74HC245D SMD IC NXP SOP20 74245 74HC245D-SOIC-20-300mil

Product Overview:

A surface-mount, 8-bit (octal) non-inverting bus transceiver integrated circuit designed for asynchronous bidirectional communication between data buses. It utilizes direction control and output enable inputs to manage data transmission, making it highly effective for isolating or interfacing memory and I/O devices on a shared system bus.

Core Specifications:

Manufacturer: Nexperia

Package Type: Available in various packages, including SO20, SSOP20, TSSOP20, and DHVQFN20

Function: Octal Bus Transceiver (3-State)

Input Channels: 8-Bit Bidirectional Bus Ports (A and B)

Control Interface: Direct Logic Input (Direction Control [DIR] and Output Enable [$\bar{\text{OE}}$])

Features:

• Wide supply voltage range: 2.0 V to 6.0 V (74HC245)

• Octal bidirectional bus interface with non-inverting 3-state outputs

• Ultra-low CMOS power dissipation

• High noise immunity configuration

• Input logic levels optimized for CMOS (74HC245) or TTL compatibility (74HCT245)

• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

• Robust ESD protection: HBM exceeds 2000 V, MM exceeds 200 V

• Input clamp diodes enable the use of current-limiting resistors to interface with over-voltage inputs

Applications:

• Bidirectional microprocessor bus interfacing and isolation

• Digital system signal buffering and expansion

• High-speed data routing and memory bus management

• Voltage level translation and logic subsystem interfacing
