Manufacturer:

National Semiconductor

File Size:

210.74 KB

Description:

Synchronous 4-Bit Binary Counters

Features

* Y Y Y Y Y Y Y Y Y Y Synchronously programmable Internal look-ahead for fast counting Carry output for n-bit cascading Synchronous counting Load control line Diode-clamped inputs Typical propagation time clock to Q output 14 ns Typical clock frequency 32 MHz Typical power dissipation 93 mW Alternate

Applications

* without additional gating Instrumental in accomplishing this function are two count-enable inputs and a ripple carry output Both count-enable inputs (P and T) must be high to count and input T is fed forward to enable the ripple carry output The ripple carry output thus enabled will produce a high-l
