LTTL SERIES Series 54L00/74L00 Low-power Transistor-Transistor Logic The 54L00/74L00 range is a series of low-power general purpose integrated circuit functions which are fully compatible with the 5400/7400 range of TTL. The range of circuits consists of 26 equivalents to the most popular TTL functions. The characteristics of the range are low power dissipation (typically 1mW per gate) combined with medium speed (typical propaga- tion delay 33ns). All circuits are fully interchangeable with other manufacturers ranges of 541L/74L low-power TTL. Table 1 on page 3 gives details of the package configurations and operating temperature ranges available for this range of circuits.
