PLC18V8Z
DESCRIPTION
The PLC18V8Z is a universal PAL® device featuring high
performance and virtually zero-standby power for power sensitive
applications. They are reliable, user-configurable substitutes for
discrete TTL/CMOS logic. While compatible with TTL and HCT
logic, the PLC18V8Z can also replace HC logic over the VCC range
of 4.5 to 5.5V.
The PLC18V8Z is a two-level logic element comprised of 10 inputs,
74 AND gates (product terms) and 8 output Macro cells.
Each output features an “Output Macro Cell” which can be
individually configured as a dedicated input, a combinatorial output,
or a registered output with internal feedback. As a result, the
PLC18V8Z is capable of emulating all common 20-pin PAL devices
to reduce documentation, inventory, and manufacturing costs.
A power-up reset function and a Register Preload function have
been incorporated in the PLC18V8Z architecture to facilitate state
machine design and testing.
With a standby current of less than 100µA and active power
consumption of 1.5mA/MHz, the PLC18V8Z is ideally suited for
power sensitive applications in battery operated/backed portable
instruments and computers.
The PLC18V8Z is also processed to industrial requirements for
operation over an extended temperature range of -40°C to +85°C
and supply voltage of 4.5V to 5.5V.
