54AC16245 16-BIT BUS TRANSCEIVERS WITH 3-STATE OUTPUTS

description
The ’AC16245 are 16-bit bus transceivers organized as dual-octal noninverting 3-state transceivers designed for asynchronous two-way communication between data buses. The control function implementation minimizes external tim ing requirements.
These devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the direction control (DIR) input. The output-enable input (OE) can be used to disable the devices so that the buses are effectively isolated.
The 74AC16245 is packaged in TI’s shrink small-outline package, which provides twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit-board area.
The 54AC16245 is characterized for operation over the full military temperature range of –55°C to 125°C. The 74AC16245 is characterized for operation from –40°C to 85°C.

54AC16245 Rad-hard advanced high-speed 5 V CMOS logic series

Description
The 54AC and 54ACT series represent over 60 product types with different high-speed CMOS functions, specifically designed to meet the radiation requirements of the aerospace industry. They include a large set of gates, flip-flops, multiplexers, counters, bus interfaces, and several other functions. Their radiation hardness, immunity from single event latch-up (SEL) and single event upset (SEU), and housing in hermetic packages make them suitable for the most difficult environmental conditions. The complete specification for each type is available from the DSCC web site: www.dscc.dla.mil. STMicroelectronics guarantees full compliance of qualified parts with these DSCC specifications.

Features
■ 2 to 6 V operating voltage
■ High speed TPD = 4.5 ns (typ.)
■ Low DC power dissipation: 8 µA max.
■ Symmetrical 24 mA output characteristics
■ High noise immunity: 28% of min. VCC
■ Power-down input protection
■ Balanced propagation delays
■ Improved electrical latch-up immunity
■ Controlled rise and fall times
■ Operating temperature: - 55 to 150 °C
■ Hermetic packages
■ Rad-hard: 300 kRad TID at any Mil1019 dose rates
■ SEL immune to 110 MeV/cm²/mg LET ions
■ RHA QML-V qualified
■ Same die and electrical specification for engineering and flight models
