74F219A64-bit TTL bipolar RAM, non-inverting (3-State)

FEA TURES

•High speed performance

•Replaces 74F219

•Address access time: 8ns max vs 28ns for 74F219

•Power dissipation: 4.3mW/bit typ

•Schottky clamp TTL

•One chip enable

•Non–Inverting outputs (for inverting outputs see 74F189A)

•3–state outputs

•74F219A in 150 mil wide SO is preferred options for new designs

•C3F219A in 300 mil wide SOL replaces 74F219 in existing

designs

DESCRIPTION

The 74F219A is a high speed, 64–bit RAM organized as a 16–word
by 4–bit array. Address inputs are buf fered to minimize loading and
are fully decoded on chip. The outputs are in high impedance state
whenever the chip enable (CE) is high. The outputs are active only
in the READ mode (WE
complement of the stored data.

1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type.

2. All typical values are at V

3. Not more than one output should be shorted at a time. For testing I
