FEATURES
74F2952, 74F2953
Registered transceiver, non-inverting (3-State) Registered transceiver, inverting (3-State)
DESCRIPTION
The 74F2952 and 74F2953 are 8-bit registered transceivers. Two 8-bit back-to-back registers store data flowing in both directions between two bi-directional buses. Data applied to the inputs is entered and stored on the rising edge of the Clock (CPXX) provided that the Clock Enable (CEXX) is Low. The data is then present at the 3-State output buffers, but is only accessible when the Output Enable (OEXX) is Low. Data flow from `A' inputs to `B' outputs is the same as for `B' inputs to `A' outputs. TYPICAL SUPPLY CURRENT (TOTAL) 105mA 105mA
* 8-bit registered transceivers * Two 8-bit, back-to-back registers store data moving in both
directions between two bidirectional buses

each register
* 74F2952 non-inverting * 74F2953 inverting * AM2952/2953 functional equivalent * `A' outputs sink 24mA and source 3mA * `B' outputs sink 64mA and source 15mA * 300 mil wide 24-pin Slim DIP package

NOTES: 1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type. 2. All typical values are at VCC = 5V, Tamb = 25C. 3. Not more than one output should be shorted at a time. For testing IOS, the use of high-speed test apparatus and/or sample-and-hold techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any sequence of parameter tests, IOS tests should be performed last.
