DM74ALS05A Hex Inverter with Open Collector Outputs

DM74ALS05A

Hex Inverter with Open Collector Outputs

General Descript ion

This de vice con tain s six i ndepe ndent gates, each o f whi ch

performs the logic INVERT function. The open-collector

output s require exter nal pull-up resi stors for prope r logical

operation.

Pull-Up Resistor Equations

Where: N1 (IOH) = total maximum output HIGH current

for all outputs tied to pull-up resistor

2 (IIH) = total maximum input HIGH current

for all inputs tied to pull-up resistor

N3 (IIL) = total maximum input LOW current for

all inputs tied to pull-up resistor

Features

■Switching specifications at 50 pF

■Switching specifications guaranteed over full tempera-

ture and VCC range

■Advanced oxide-isolated, ion-implanted Schottky TTL

process

■Functionally and pin for pin compatible with Schottky

and low power Schottky TTL counterpart

■Improved AC per forma nce over Schottky and low power

Schottky counterparts

Ordering Code:

Devices also available in Tape and R eel. Speci fy by appending the s uffix let t er “X” to the o rdering c ode.

Absolute Maximum Ratings(Note 1)

Note 1: The “Abs olute Maxim um Ratings ” are those valu es beyond w hich

the saf ety of the device cannot be guarante ed. The device s hould not be

operated at these limits. The parametric values defined in the Electrical

Characteristics tables are no t gua rant eed at the absolute maximum rati n gs.

The “Re comme nded Operat ing Co ndition s” table will define the cond itions

for actu al device operation.
