HD74HCT1G00
2–input NAND Gate
ADE-205-301B (Z)
3rd. Edition
April 2001
Description
The HD74HCT1G00 is high speed CMOS two input NAND gate using silicon gate CMOS process. With
CMOS low power dissipation, it provides high speed equivalent to LS–TTL series. The internal circuit of
three stages construction with buffer provides wide noise margin and stable output.
Features
•
The basic gate function is lined up as hitachi uni logic series.
•
Supplied on emboss taping for high speed automatic mounting.
•
TTL compatible input level.
Supply voltage range : 4.5 to 5.5 V
Operating temperature range : –40 to +85°C

Notes:
Tstg
The absolute maximum ratings are values which must not individually be exceeded, and
furthermore, no two of which may be realized at the same time.
1. The input and output voltage ratings may be exceeded if the input and output clamp-current
ratings are observed.
2. This value is limited to 5.5 V maximum.
3. The maximum package power dissipation was caluculated using a junction temperature of
150°C.
