93L10/93L16
BCD Decade Counter/4-Bit Binary Counter
General Description
The 93L10 is a high speed synchronous BCD decade coun-
ter and the 93L16 is a high speed synchronous 4-bit binary
counter. They are synchronously presettable, multifunction-
al MSI building blocks useful in a large number of counting,
digital integration and conversion applications. Several
states of synchronous operation are obtainable with no ex-
ternal gating packages required through an internal carry
lookahead counting technique.
