74F219
64-Bit Random Access Memory with 3-STATE Outputs
General Description
The 74F219 is a high-speed 64-bit RAM organized as a 16-
word by 4-bit array. Address inputs are buffered to mini-
mize loading and are fully decoded on-chip. The outputs
are 3-STATE and are in the high-impedance state when-
ever the Chip Select (CS) input is HIGH. The outputs are
active only in the Read mode. This device is similar to the
74F189 but features non-inverting, rather than inverting,
data outputs.
Features
s
3-STATE outputs for data bus applications
s
Buffered inputs minimize loading
s
Address decoding on-chip

Diode clamped inputs minimize ringing
s
Available in SOIC (300 mil only)
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter "X" to the ordering code.

Absolute Maximum Ratings
(Note 1)
Recommended Operating
Conditions
Note 1: Absolute maximum ratings are values beyond which the device
may be damaged or have its useful life impaired. Functional operation
under these conditions is not implied.
Note 2: Either voltage limit or current limit is sufficient to protect inputs.
