DM74ALS1000A Quadruple 2-Input NAND Buffer

DM74ALS1000A

Quadruple 2-Input NAND Buffer

General Descript ion

These devices contain four independent 2-input buffer/driv-

ers, eac h of which perfor ms the logic NAN D function. The

DM74ALS1000A is a buffer/driver version of the

DM74ALS00A.

Features

■Switching specifications at 50 pF

■Switching specifications guaranteed over full tempera-

ture and VCC range

■Advanced oxide-isolated, ion-implanted Schottky TTL

process

■Improved line receiving characteristics

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 “Absolute Maximum Ratings” are those values beyond which

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 not 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.
