Product Summary

The 74ACT11245NT octal bus transceiver is designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements. The 74ACT11245NT allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction control (DIR) input. The output-enable (OE) input can be used to disable the 74ACT11245NT so that the buses are effectively isolated.

Parametrics

74ACT11245NT absolute maximum ratings: (1)Supply voltage range, VCC:–0.5 V to 7 V; (2)Input voltage range, VI:–0.5 V to VCC + 0.5 V; (3)Output voltage range, VO:–0.5 V to VCC + 0.5 V; (4)Input clamp current, IIK (VI < 0 or VI > VCC):±20 mA; (5)Output clamp current, IOK (VO < 0 or VO > VCC):±50 mA; (6)Continuous output current, IO (VO = 0 to VCC) :±50 mA; (7)Continuous current through VCC or GND:±200 mA; (8)Storage temperature range, Tstg:–65 to 150℃.

Features

74ACT11245NT features: (1)3-State Outputs Drive Bus Lines Directly; (2)Inputs Are TTL-Voltage Compatible; (3)Flow-Through Architecture Optimizes PCB Layout; (4)Center-Pin VCC and GND Configurations Minimize High-Speed Switching Noise; (5)EPIC (Enhanced-Performance Implanted CMOS) 1-μm Process; (6)500-mA Typical Latch-Up Immunity at 125℃; (7)Package Options Include Plastic Small-Outline (DW), Shrink Small-Outline(DB), and Thin Shrink Small-Outline (PW) Packages, and Standard Plastic 300-mil DIPs (NT).
